First, thanks to Mark Kopp for posting his article on this topic, it is very
thorough and should help a lot of people.
Also I wanted to add a perspective that I've maintained ever since CTC
released its first DVD. No customer needs to have any concerns when ordering
DVDs from CTC, each is produced with the highest quality.
Some do take shortcuts in creating DVDs, and, yes, now those shortcuts are
beginning to surface, as educators or patrons begin to use the DVDs of
lesser quality. However, those DVDs of lesser quality should not be used to
frighten customers away. As a producing-distributor, I never take shortcuts
when it comes to creating DVDs or Digital Files. Some may take shortcuts by
not creating menus for their DVDs, some may use less expensive DVDs as
masters, some may not use the best machines to duplicate their DVDs, some
may not encode the DVDs at the highest quality. These are key reasons why a
lot of those DVDs of lesser quality don't work on DVD players. Taking
shortcuts may save them some money upfront, but in the long run it's not a
good decision, it's not good business. Customers can be assured that CTC
takes no shortcuts when producing its DVDs.
As this article confirmed, creating a DVD is not a 100% guarantee that it
will work on every player, and for that reason CTC will replace any DVD that
may not work for up to a year Free of Charge; however, because of the high
standards we use in creating our DVDs, our utilization % is extremely close
to 100%.
Customers can increase the %s by working with vendors who don't take
shortcuts and who guarantee a replacement for any possible incompatibility.
Sincerely.
Chip Taylor, President

(New!) Some DVD-Rs burn too slowly, or not at all on my burner...
THE PROBLEMS
Many models of DVD burners have had problems burning more than a
few, limited brands of DVD-R discs. And, sometimes discs that are sold as
being 2X or 4X rated only burn at 1X speeds. And also, after being recorded
many DVD-R discs would either not play or produce playback errors in some
DVD players. Here are some of the complaints we hear most often:
a.. "My 8X DVD Writer won't even recognize many brands of 8X
DVD-Rs, or only burns them at 4x or 2x, sometimes even 1x... are these bad
discs?"
b.. "My 4X DVD Writer won't even recognize many brands of 4X
DVD-Rs!"
c.. "My 4X DVD Writer burns some 4X DVD-Rs at 4X and others at
only 1X!"
d.. "My 2X DVD Writer burns all 4X discs at 1X... why not 2X?"
e.. "My DVD Writer shows lots of errors when burning 2X or 4X
DVD-Rs!"
f.. "My DVD Writer seems to burn at 4X okay, but then the discs
don't play well!"
g.. "My old 103/104 model burned these same DVD-R discs at 2X, and
now my new 105/A05 only burns them at 1X -- what's going on?"
BACKGROUND
Fixes are now available for many models of DVD burners that will
address some of these issues (see if your burner model is listed below). The
DVD recording industry is still evolving, and important improvements in how
well discs, burners and players work together are being made almost every
week. As the factories which produce the various brands of burners and discs
and players learn about ways to make their products work better, they add
these improvements into newer models they are shipping, and also release
"firmware upgrades" where possible to add these improvements into burners
and players they have already sold. Some of these problems are impossible to
fix, but great improvements are being made.
SOLUTIONS
The newest firmware upgrades from burner manufacturers can improve
your burner's compatibility with DVD-R discs, making it possible to burn
them and play them with fewer errors and at higher speeds. you simply
download a free upgrade from your manufacturer, install it into your burner,
and then do some more tests. In many cases, after installing the latest
firmware upgrades you will find...
After Installing the New Firmware...
a.. Most 8x or 4x discs will now burn at their full top speed
rating
b.. Many 2X DVD-R discs that would only burn at 1X will now burn
successfully at 2X speed
c.. Many 4X DVD-R discs that would not burn at all, will now burn
successfully
d.. Many 4X DVD-R discs will now "fall back" to 2X instead of 1X
when 4X speed is not possible
e.. Many 2X rated DVD-R discs will now burn at 2X instead of only
1X or not at all
f.. Overall writing or reading disc errors will be reduced on most
disc brands
WHERE TO DOWNLOAD FIRMWARE UPGRADES
DVD Burner Drive Updates - Most problems with drive performance and
disc compatility can be solved by upgrading your drive to the latest
firmware by downloading a small free updater file from the manufacturer, and
running it on your computer. Updates are free, and usually come out several
times a year. Even new drives usually need new updates applied to fix
problems. New firmware will update the settings on your drive's internal
firmware chip to fix bugs and improve performance with more brands of discs.
We maintain a page to help you find the latest firmware for your DVD burner
model, and keep it up to date with latest download links. You can find
recent firmware free download links on our own Burner Compatibility Updates
page. On our page, click the brand at the top of the page to jump to your
brand of drive. This will show you a download link for firmware updates, and
also a list of our recommended compatible discs by Stock Nos. for your
particular burner - be sure to check this important page often. You can also
find recent updates at Firmware-Flash.com. On that page, click the "DVD
Recorder" link under your brand of drive, and then find your model listed on
the next page.
WHAT IS FIRMWARE? -- BACKGROUND OF HOW DVD WRITERS WORK
WITH DIFFERENT BRANDS OF DISCS
DVD burners optimize their ability to write to different brands of
DVDs by internal "write strategies" that control the laser power and pulse
settings to maximize its accuracy with each different dye formula, reflector
density and plastic doping chemistry for each brand of blank DVD disc. When
a disc is inserted, the drive reads the factory media ID off the disc and
queries its internal list of known disc brands and write strategies. If the
disc is listed, then it uses the write strategy for that disc. If a write
strategy for a particular disc brand is not present in the drive's firmware,
it tries to estimate how best to write to the disc by writing to the small
re-writable "power calibration" area on each unknown disc type to see which
power setting might produce best results for the unknown disc brand. In some
cases, the firmware is unable to produce reliable burning with a particular
disc brand, and rejects the disc as having a "power calibration error" or
"illegal disc" or a similar error. This error is generally not related to
disc quality issues, but is simply a result of the drive not having the
latest firmware in it that lists the particular disc brand.
FIRMWARE UPGRADES
From time to time, drive makers test additional brands of DVD discs
and then update their firmware with new write strategies for those newly
tested discs, enabling their drives to work with more brands of DVD discs.
All DVD writer owners need to frequently check with their drive manufacturer
to see if there is a new firmware upgrade available for their drive. That
way they can expect to enjoy working with more brands of discs, and more
reliably with the discs that they already can use.
HOW TO FIND YOUR DRIVE'S MODEL and FIRMWARE LEVEL -- For Windows
computers, right click on MY COMPUTER, then click on the HARDWARE tab, then
click on the DEVICE MANAGER button, then click to highlight your drive from
the list of devices, and select PROPERTIES, then SETTINGS if shown. You
should see your drive manufacturer, model and firmware revision level
listed. For Macintosh computers, go to the Apple Menu at the upper left of
your screen, and pull down to activate the Apple System Profiler. Click on
the DEVICES AND VOLUMES tab at the top, then find the line down the left
side that lists the ATA Device for your Superdrive, and click on the small
ARROW to expland that line. It should now show your drive model,
manufacturer and firmware revision number.
(1) How can I make copies of my DVD movies or games?
IMPORTANT
We no longer sell DVD copying software--here's why... Some recent
USA court decisions have backed up the arguments made by the Recording
Industry Association of America, and various other trade associations, that
all movie and music disc copying is unlawful. Whether this line of reasoning
will stand for many years to come remains to be seen. Retail software
companies like DVD X COPY which had previously facilitated such copying have
been ordered to change their programs to stop the practice for any copy
protected DVD movie or audio disc. Other companies and software makers may
face similar orders in the future, or perhaps future appeals and laws may
return to the idea of "fair use" copying. The previous interpretations of
"fair use" in copyright laws permitted making ONE copy of a recording as a
backup of a disc or tape you actually own, for your own use. They did NOT
permit making a copy of a disc you did not own, nor re-distributing any
copies to others. Remember that making more than one copy of any disc you
own is certainly against the law and "fair use". And, making a copy of a
friend's disc, or distributing copies to friends is directly against the
law. Please use these DVD and CD creation software applications and devices
in legal ways. Respect the intellectual property rights of the authors of
these discs. We do not support nor encourage unethical or illegal copying of
DVDs or CDs or tapes, and we will not assist people in those efforts.
Freeware DVD Backup Programs -- If legal to use in your state or
country, you may want to download these programs below. Check your local
laws if uncertain about whether you can use these programs in your area.
The two programs below are very easy to use, and dependable for most
users with Windows computers. If your DVD is a short movie less than 2 hours
long, and less than 4.7 GB in total size, then it will fit onto one DVD-R or
DVD+R and you can use DVD Decrypter. If your original DVD is longer than two
hours or its total size is bigger than 5GB, then you need to use DVD Shrink.
DVD Shrink will let you squeeze these bigger DVDs into one DVDR disc. You
will be able to choose which languages, menus, trailers and titles to remove
and what final quality setting to use. Removing most extras from these
longer movies often lets you get a final quality of 90% or so, which is
still quite enjoyable. DVD Shrink does require that you have Nero already
installed in your computer, since it automatically depends on Nero's burn
engine to do the final burning of your DVDR disc. If you don't have Nero
yet, you can use the link below to download a trial version. After 30-days,
it costs $60 for the serial number.
a.. For DVD5 "Short" Movie Disks -- up to 4.7gb 2 hour movies onto
one DVD. Requires no added software.
b.. DVD Decrypter 3.1.9.0 (January, 2004)
a.. Download DVD Decrypter 3.1.9.0
c.. Read a How-to-Use DVD Decrypter Guide
d.. For DVD9 "Long" Movie Disks -- squeezes 9gb several hours onto
one DVD. The recording function requires Nero, see below.
e.. DVD Shrink 3.1.4 (January, 2004)
a.. Download 3.1.4 - Latest version
f.. Read a How-to-Use DVD Shrink Guide
a.. Nero Suite 6.3.x -- required to use DVD Shrink above. If you
already have an older Nero version installed, you may not need this
download.
b.. Nero 6.3.x 30-day Trial Download (Serial Number costs $60
after 30 days)
Other Programs -- The two programs above are all most users will
every need. However, many other programs are also available, some free and
some in trial or retail versions. See them described in the big list on the
http://www.dvdrhelp.com/tools/ page.
DVD burners are made to produce your own ORIGINAL DVD movies (such
as wedding videos, home movies, company presentations, etc.), to record
backups of VHS movies and television shows, and so on. However, when it
comes to duplicating DVDs, burners and DVD movie or game discs are designed
to make it difficult for you to make direct copies.
So, DVD burners are NOT capable of DIRECTLY copying a DVD movie or
game disc, since the discs are scrambled, and the CES de-scrambling codes
are located on a part of the disc that cannot be mechanically copied by the
burners, but can be read by all DVD players. Those codes are required to
decode them, so they will play on the DVD players.

(2) Which DVD burner and discs are best?
The recordable DVD world is now a bit too complicated, something
like the video tape or CD-R world was many years ago. Take a look at a few
dozen of the most popular DVD Writers and the types of DVD recordable discs
they can work with at... Our "Which Burner with Which DVD?" Page
Recommended DVD Burner -- The new Pioneer DVR-107 and their previous
DVR-106D model are the most popular and dependable burners/players for most
users. They burns or creates 4.7gb DVD±R write-once discs at up to 4x speed
(8x for the new DVR-107) and DVD±RW erasable discs at 2x (4x for the
DVR-107). They also creates or burns CD-R and CD-RW discs. It plays DVD-R,
DVD-RW, CD-R, CD-RW and both DVD Video and DVD Music, CD Video and CD music
discs. They are internal ATAPI EIDE drives that work in the great majority
of Windows PCs and G4 Macs. Installation is easy, and is "plug-n-play", only
taking a few minutes. If you can install a hard drive, you can install this
DVD burner. An optional external Firewire/USB2.0 enclosure can also be
ordered with the drive if you intend to use it on Notebook computers or want
to make the drive usable on more than one PC. See our DVD burners at... Our
DVD Burner Page.
Regarding DVD-R and player compatibility, see our below... Which DVD
players can play +/- DVDR's?
The majority of DVD players now in the market appear to play at
least one type of DVD±R 4.7gb "general purpose" type discs well.
We sell all formats of recordable DVD discs, including DVD-R,
DVD-RW, DVD+R, DVD+RW, DVD-RAM, and so on. So whichever burner you buy, we
can sell you the discs you need at very competitive prices.
There are other burners out in the market, including the Panasonic
drives which burn only DVD-R/W and DVD-RAM discs. The advantage to this
recorder is that it can edit DVD video using the fast DVD-RAM discs, and
then produce a final DVD-R disc which will play on most popular consumer DVD
players. If you do a lot of DVD video editing you may want to consider this
drive. However, many video editors prefer to edit their video on their fast
hard drives since hard drives are so cheap these days, and prefer the
versatility of the Pioneer DVR-A04 above for burning and playing many
formats of DVDs and CDs. A major problem for many users is that these drives
require much more expensive DVD-R discs than usual, due to their use of a
DVD-RAM laser that was designed primarily to write to the metallic bottomed
DVD-RAM discs. If you are intending to use your burner to write to DVD-R
discs, don't by a DVD-RAM machine. It will end up costing you hundreds or
thousands of dollars more due to its -R reflectivity issues.
If we were entering the market at this time, we would buy the
most-popular Pioneer DVR-107 burner. For editable discs, we'd use the
DVD-RWs it burns. For DVD "releases" for public or company-wide
distribution, we'd use the 4.7 GB DVD-Rs it produces (understanding that
about many DVD players may not play a particular brand of blank DVD-R or
DVD+R disc). Over time, as the market matures, more and more consumer DVD
players will play the DVD-R discs. It is priced right, and is very
versatile. Then, we would expect to replace it with an all new drive
sometime in 18-24 months.

(3.a) Which DVD players can play +/- DVDR's?
Model by Model Lists of Reported Features
by DVDRHELP.COM
Reported DVD Compatibility (as of Feb. 2004)
60% DVD-R "minus" COMPATIBILITY - 2204 of ALL 3688 TOTAL DVD PLAYERS
(click to check your model of DVD player for Minus or General compatibility)
47% DVD+R "plus" COMPATIBILITY - 1731 of ALL 3688 TOTAL DVD PLAYERS
(click to check your model of DVD player for Plus compatibility)
In practice, as shown on the pages linked here, about 53% of today's
DVD players don't work with either DVD+R or +RW discs, a number which is
substantially more than the "minority" they admit to on the page above.
And, the number for DVD-R and DVD-RW discs is only a bit better,
with as many as 40% of today's DVD players not working with the "general" or
"minus" type of blank DVD recordable.
However, the percentages are improving. More and more of today's
current DVD player models actually support playing most DVD-R and most DVD+R
discs. The number of DVD players actually on the shelves in stores that play
recordable DVDs is around 90%. Only a few models don't play at least some
brands and kinds of blank, recordable -R or +R discs.
It is our experience that thousands of our customers do in fact
report greater DVD player compatibility of the DVD-R and DVD-RW "minus" or
"general" type discs, compared to the "plus" type +R or +RW discs. Some
sources report similar findings of about 60% player compatibility for DVD-R,
and only 47% or so for the DVD+R. As always, your own compatibility may
vary...
Furthermore, the actual performance of any particular BRAND of disc
can vary within a type, due to variations in proprietary (patented) design
issues relating to differing bottom dyes used, dye laser light absorption
factors and silver reflectivity values. As a result, any particular brand
may not perform with a particular model of DVD player, even though the
player is designed to theoretically handle some brands of "plus" or "minus"
type of blank DVD.
The DVD+RW Alliance group that controls that "plus DVD" recording
industry claims that their disc format is at least theoretically compatible
with ALL of the DVD players. See their page at...
http://www.dvdrw.com/why/compatibility.htm.
DVD+R and DVD+RW are compatible!
DVD+R/+RW video recorders are based on the standardized DVD-Video
format currently used by the millions of DVD players sold worldwide. Because
DVD+RW uses only one mode for recording and editing, every recording you
make is DVD-Video compatible. There is no need for a player explicitly to
support DVD+RW or to indicate compatibility with DVD+RW on the front of the
player by means of a logo. The reason you see this on other recordable DVD
formats is because they require specially adapted players to make their
recordings compatible with other machines. The logo lets you know which
players will work with your recording. In contrast, even if a player is not
indicated explicitly as being DVD+RW compatible, it is very likely it will
still play the disc because we use the standardized DVD-Video format.
On a physical level, recordable and rewritable DVDs are almost
identical to normal, pre-pressed DVDs. However, due to the nature of
recordable and rewritable media (such as a different degree of laser
reflectivity), a minority of players might not be able to play such discs
correctly. As a guideline to which players can and cannot play DVD+R and
DVD+RW, so-called compatibility overviews were created.

(3) Why do my DVD-Rs only play on some DVD players and not others?
While the DVD Movie and Game discs you buy or rent in the stores
appear to be "silver" or "gold", they are usually made from aluminum
coatings, over a clear layer that has been mechanically pressed with pits or
holes to encode the data that the lasers in the DVD players decode into
music and video signals. DVD Video discs that are made this way do not
require the light sensitive dye layer used in DVD-R discs, and so they
appear clear on the bottom, or nearly so. They never have to be "burned".
By contrast, the recordable DVD-R discs use a dark dye layer to
absorb the higher powered laser in DVD burners to create the tiny pits or
holes that encode the disc's data. This dye layer causes problems for some
cheaper and older DVD players, but it is none-the-less required to "burn"
the DVD-R. Most of today's DVD Players now are able to read both the clear
bottomed DVD movie and game discs, and also the colored dye bottomed DVD-R
discs. We have a page that lists over 200 DVD players now in the market,
rating their DVD-R playing compatibility. Approximately 97% of today's DVD
players actually being sold at the moment, can play DVD-R type discs, while
about 86% will play DVD+R discs. When you count ALL THE PLAYERS still in
use, then the numbers drop down to 47-60% compatibility... but the older
machines are being replaced by newer more compatible machines pretty fast.
You can see more info on DVD players and DVD-R/+R compatibility discussed
below...
As far as the "quality" of the DVD-R discs themselves, we constantly
test our own generic DVD-Rs to ensure their high-quality, low-errors, and
consistent workability with popular players and burners. We get far less
than 1% of them returned. See our FULL list of all our general purpose
DVD-Rs at... General DVD-Rs List
The blank DVD-Rs we call "Pro-Grade" are our best quality discs,
with the lowest error rates and highest player/burner compatibility. See our
list of Pro-Grade general purpose DVD-Rs at... Pro-Grade DVD-Rs
Our "Standard Grade" DVD-Rs are less expensive, but may not be
compatible with a few brands of DVD burners and players, such as the
Panasonic DMR-EM20/30 series. Otherwise, the discs are of reliable,
consistent quality for most users. See our list of Standard general purpose
DVD-Rs at... Standard Grade DVD-Rs
• Back to Top
(4) Which DVD recordable discs are the most compatible with players?
Not all DVD Players are capable of playing or reading a DVD-R format
recordable DVD disc. And, those that can play at least one kind or brand of
DVD-R may not be able to play other brands, regardless of quality.
Most Can... A glance at the lists linked here will show you that
about 97% of today's DVD players actually on shelves can handle DVD-Rs. As
you may know, the store-bought DVD Movies and Games you have were pressed
mechanically, like old-fashioned vinyl LP records. By contrast, your
recordable DVD-R discs are "burned" with a laser, and have a slightly
different format than the retail DVDs you buy or rent. Playing your burned
DVD-Rs requires an extra feature or two that MOST but not all players have.
Below is our current detailed list, of existing DVD player brands and models
with an evaluation of their ability to play your DVD-R recordings.
Little Differences Matter... There are subtle differences between
the dye formulas and top reflectors used among DVD-R manufacturers, as each
company struggles to find a "middle ground" that straddles the wide
variations in laser types and logic circuitry used by DVD players and
burners. Even though two general purpose type DVD-Rs may be well made, they
may have been made to slightly different standards by their makers; each
deciding to be more or less compatible with certain brands of players and
burners.
How Do We Know? This information has been obtained from many
sources, including our own tests and information from users such as
yourself. It is constantly updated. While we cannot absolutely guarantee
that your recordings will play on each of these players, we hope that this
partial list of over 200 different DVD players will help you see the present
state of the DVD player market.
No Guarantees... Remember that this list is merely a guide to DVD-R
and DVD player compatibility. It does not, nor cannot guarantee that any one
DVD-R disc is compatible with a particular player. It merely reports that
the player has been reported to work with at least ONE type or brand of
general purpose DVD-R or DVD-RW.
Try a Few... As always, we recommend that you buy small quantities
of several types of general purpose DVD-R discs to determine which will work
best with your own burner and available target DVD players. The DVD
recordable market is constantly changing and requires that you be willing to
invest a minimum of time and a modest "testing budget" to gain the
experience and knowledge you need to fully enjoy and benefit from this
exciting new technology. If you wish, you may want to order one of our
affordable Sampler DVD Paks (Each sampler pak includes FREE 2nd Business Day
Air Shipping at no additional charge, and is non-returnable.)
Share Your Wisdom... If you wish to provide us with another model
that you have tested personally and can provide reliable information about,
or you have found an error in the list below, feel free to email us your own

(5) What is the difference between DVD-R/DVD-RW, DVD+R/DVD+RW and
DVD-RAM discs?
DVD-R and DVD-RW
These 2 disc types were created by the DVD Forum ( see it at DVD
Forum Site ).
Both DVD-R and DVD-RW types generally come in the single-sided,
single layer 4.7 GB capacity, which is roughly equal to 120-minutes of
standard playing time.
You can also now find 9.4 GB double-sided discs entering the market,
although there are no players which will automatically play both sides of
the disc without ejecting it and turning it over. Eventually, there will be
DVD-R discs available that will hold around 20 GB of data, recorded into two
layers on each side of the disc. At this time, these 20gb discs are not yet
available.
The most common DVD-R is a write-once 4.7gb disc that comes in two
sub-types -- "general purpose" and "authoring". The general purpose discs
are part of the industry's copy-protection scheme, which employ CES
scrambling to protect movies and music and game discs from being copied.
These discs can only be burned by general purpose type DVD writers such as
the Pioneer DVR-A04/104/A03/103 machines, the Panasonic LF-D311 and D321,
Apple Superdrive, etc. Such machines cannot copy the playback descrambling
codes on DVD movies or game discs, so they cannot be easily copied.
Authoring DVD-Rs must be burned by the Pioneer DVR-S201 DVD Writer, which
produces non-copy protected discs for use in the industry for professional,
retail DVD duplicators and distributors. Once recorded, either a general or
authoring DVD-R can be played on most DVD players (if the player is DVD-R
compatible). See our DVD-R discs' info and price offerings at... General
DVD-R Discs Info
By contrast to the write-once DVD-R types, the DVD-RW is fully
re-writable or eraseable up to 1,000 times. However, unlike the older
DVD-RAM format, these particular erasables are NOT "random access", meaning
that you cannot erase bits and pieces of them. Instead, you have to
completely erase the whole disc to reuse it. The DVD-RW can be played on
many DVD players, but not quite as many as the DVD-Rs. Of course, DVD-RAM
discs are playable on only a few types of DVD players. See our DVD-RW discs'
info and price offerings at... General DVD-RW Info
Most DVD-R burners like the Pioneer DVR-104s and compatibles, can
also burn DVD-RW discs. An exception is the popular Panasonic DVD burners,
which burn only DVD-R and DVD-RAM. This drive is great for users who want
both data storage and editing features from DVD-RAM, and DVD-R production
capabilities for disc copying and distribution.
DVD-R is the most popular format for most Windows users, and is
almost universally accepted by Mac users as their standard DVD recordable
format.
DVD+R and DVD+RW
These two types were created and are backed by the DVD+RW Alliance
( see it at DVD+RW Alliance Site ). A few companies who back the DVD Forum
(above) are also active in the DVD+RW Alliance, but the two standards are
not compatible.
The oldest "plus type" DVD is the DVD+RW. It, like DVD-RW, is a
rewriteable 4.7 GB DVD kind of disc. DVD+RW, does have a couple of technical
advantages -- (1) lossless linking (which enables some editing after
recording without a full erasure that DVD-RW requires), (2) up to 2.4X
recording speeds on some burners, and (3) a special drag-and-drop file
support on the desktop (otherwise known as DVD+MRW). Unfortunately, the
DVD+R disc type does NOT even begin to compare with DVD-R as far as DVD
playback compatibility. However, the actual level of DVD workability on
players of DVD+RW is claimed to be about equal to DVD-RW. Of course, even
so, neither the DVD+R nor the older DVD+RW discs are as popular as DVD-R and
DVD-RW are. See our DVD+RW disc info and prices offerings at... DVD+RW
Product List
The newer DVD+R write-once type disc is aimed at becoming more
compatible with DVD players. However, the fact is that so far it is only
about as compatible as DVD-R discs are. Also, the DVD+R discs are more
expensive in today's market, and not burnable by "1st generation" plus-type
burners, which were designed only for the DVD+RW rewritable discs. If you
want to create +R discs, you'll need the newer "2nd generation" type
burners, such as the Sony 120A, the Ricoh 5125A, and so on. See our DVD+R
disc info and prices offerings at... DVD+R Product List
DVD-RAM
DVD-RAM is used for data backups and storage, and for editing of
video or audio content prior to the production of a final distribution DVD.
The DVD-RAM disc type is made to act a lot like a hard drive, where the disc
can be formatted for HFS+ Macintosh or Windows type computers, and so on. It
can handle 100,000 or more erasures, and should last for many years. Of
course it is not playable on many DVD players. Type 2.0 DVD-RAM discs can be
removed from their cases to enable playback on the few players in which they
are compatible. The newer DVD-RAM drives can handle any sized such disc,
including 2.6, 5.2, 4.7 or 9.4 GB discs. See our DVD-RAM disc info and
prices offerings at... DVD-RAM Product List
HOW ABOUT AN "EVERY DVD" TYPE BURNER?
Nope. Unfortunately you can't get a burner that will handle both
"general type" and "plus type" DVD recordables.
The Panasonic LF-D321/311 machines (and OEM versions packaged by
other companies using the same mechanism) offers a drive that some users
prefer. It lets you do backups, editing and temporary storage on DVD-RAM
discs, and then lets you switch to DVD-R's popular format when you want to
make discs for distribution. For editing, the DVD-RAM is very fast and
offers a drag-and-drop type ease of use like a hard drive. See the Panasonic
DVD Writers at... Panasonic DVD Burners
However, the popular Pioneer DVR-104 and its OEM compatibles such as
the Apple Superdrive also offer a combination of features -- you can burn
both CD-R and CD-RW discs, as well as DVD-R and DVD-RW discs. While you can
use DVD-RW for erasable backups, you don't have the easy file access that
DVD-RAM offers. As far as editing goes, most users simply buy bigger hard
drives to have the room for video and music edits. Hard drive prices and
speed advantages make that an attractive option. Altogether, these drives
are by far the most popular machines for most users. See the Pioneer combo

(6) Will paper DVD labels hurt my recorded DVDs?
For many years, CD-R manufacturers recommended that users NOT apply
paper labels to their newly recorded CDs. They felt that the labels'
adhesive would harm the sensitive silver reflector by tarnishing it, or that
off-center labels might cause the disc to wobble, making it unreadable.
These factors are much more important today for DVD recordable discs
than they ever were for CD-Rs. On DVD-Rs, the tiny data bubbles that encode
the video and audio data are 8-times closer together than on CDs. Even the
slightest degradation of the edges of the bubbles due to UV or heat exposure
can ruin a DVD-R. Also, even the slightest wobbling during playback can make
video tracks unreadable, or produce "jitters" or blinking, horizontal lines,
and so on. In some cases, the discs can become completely unplayable.
We recommend that if you wish to apply labels to your DVD recorded
discs, you use our "no-wobble" discs, together with an appropriate full-face
label applicator tool to help you center and prevent bubbles when applying
the labels. See these products at... No-Wobble DVD Labels
The other solution is to print directly onto the disc itself with a
high quality inkjet or thermal printer. We sell special inkjet surface DVD-R
discs. See them at... Inkjet Printable DVDs
We also sell CD/DVD inkjet printers with the pass-thru trays that
let you print directly onto the special inkjet discs... Direct-to-disc

(7) How long do recorded DVD discs last?
All DVD recordable discs are extremely sensitive to heat, UV light
and humidity. You should avoid exposing them to any extremely hot
environment such as automobile interiors in the sun, or inside near
radiators or heaters, or near an outside window, and so on.
It's best to keep all DVD-R discs stored in a cool, dry place,
closed up in a blank plastic DVD movie case. This will ensure that they last
the longest.
Avoid any abrasive, scratching or etching treatment of the disc's
top or bottom. Remember that they are much more sensitive than DVD VIdeo or
Game discs, and that even a small scratch can make them unplayable.
However, a scratched DVD-R can be destroyed in seconds, and one
exposed to high temperatures, humidity or strong UV light sources can become
unplayable within anything from a few hours to a few days. One study of
average DVD-R discs stored at 80 degrees and high humidity showed that many
of them became unplayable in only a few hundred hours. Imagine what storage
in a sun-heated car interior's "oven" at about 200 degrees would do!
Treat your recorded DVD-Rs with care. Handle them by their edges,
gently. Avoid harsh chemicals in marking pens, ink and label adhesives.
Avoid touching the top or bottom surfaces. Don't slide them across tables,
players or computer cases. Return them to their black DVD cases immediately
after playing. Don't stack DVD-Rs one on top of each other and shuffle them
like a deck of cards.
Do buy white coated DVD-Rs. The extra top coating can add a bit of
extra protection against some chemicals and minor nicks and abrasions. Do
buy gold metal reflectors when you want to get the absolute longest storage
possible. Gold does not tarnish. Silver alloy metal reflector discs can last
for many years also, especially with the white top.
With proper handling and protection during storage, a DVD-R disc can
last for longer than you will probably want to re-play them. One company
claims that its DVD-R discs can last up to 100-years or more. Store your own
DVD recorded discs carefully in a cool, dark, dry place and they should last
for many years.

(8) What are "Authoring" DVD-R discs?
Authoring type DVD-R discs are made to be compatible only with the
very expensive Pioneer DVR-S201 DVD Writer, which sells for $4,000 to
$5,000. This machine produces special DVD-Rs which are used as "mastering"
discs for professional distribution and duplication purposes. Authoring
discs are not compatible with inexpensive "general purpose" or "plus type"
DVD-R/RW or DVD+R/+RW Writers. The actual quality of authoring discs is not
necessarily better than any other. It is simply a non-copy protected disc
type, made for professional use. See our AUTHORING DVD-R discs' info and
prices at... Authoring DVD-R Discs

(9) Are your DVD-R discs GUARANTEED to be compatible with my player
or burner?
Actually NOBODY can guarantee 100% compatibility for their DVD
recordables in today's market. Why? Well ...
While the market is improving regarding burner/player/disc
compatibility and conformity with standards, it is not yet a "mature"
market.
In fact, some say there is a battle going on between major brands
such as Philips and Pioneer, with the consumer caught in the crossfire.
Unfortunately, as a result of this battle, DVD-R discs cannot be
guaranteed to be compatible with all DVD burners or all DVD players. Even
within the specific DVD recordable type, such as authoring, general purpose,
plus and DVD-RAM, a particular brand of disc may not be compatible with a
particular burner or player. The discs are only guaranteed to be free of
defects in materials or workmanship. Since you find a disc of excellent
quality to be incompatible with your particular combinations of burners,
players and software, we always recommend that you order a sampler pak
before ordering the larger spindles of discs. Anytime after upgrading your
software, firmware or changing your hardware configuration, we recommend
testing again. You may obtain an inexpensive, non-returnable sampler pak
containing several brands of recordable DVD discs at... DVD Sampler (we
include free 2nd day shipping in the cost of these paks)
About 75% of today's DVD players can play at least one kind of
DVD-R. It appears that just slightly fewer can play DVD+R discs at the
moment, although this number is slowly increasing. Perhaps 25-30% can play
some kind of DVD-RW. Next come the DVD+RW and DVD-RAM discs. See a list of
DVD players with recordable playing features at... DVD-R/W Compatible

(10) Why won't my DVD-R discs burn at 2X speed?
Unfortunately there is no official standard for the manufacturers of
2X discs. Standards are set by a group called the DVD Forum, and they DO
have a standard for 1X. The way that Pioneer gets 2X performance on some
kinds of DVD-R discs is by testing a sample of each manufacturer's discs and
tweaking their DVR-104/A04 burner's firmware for each disc. If they find an
adjustment that works for a disc brand and type, they create a modified
version of their firmware and release it on their web pages. Every few weeks
or months, there is a new firmware for the Pioneer brand DVR-104 and
DVR-A04. However, some DVR-104 units installed by other computer makers may
use different, and older, firmware. That firmware may not recognize as many
kinds of discs to operate at 2X.
FOR WINDOWS USERS -- Most of our Windows users have no problems with
the 2X speed on our 2X Pro-Grade DVD-Rs, however we have had a few Apple
owners report that they've had problems. If you're a Windows and Pioneer
drive user and have installed the latest Pioneer firmware upgrades, you
still may not be able to get 2X performance from some discs that are in fact
rated for 2X. This may be due to the condition of the disc, the version of
the creation software you're using and various other factors including
memory usage, bus and processor speed, and so on. As always, it is best to
buy a small sampler pack of DVD recordables to check for performance on your
machine. Be sure that no other programs are running other than your disc
creation software to guarantee maximum speed performance.
FOR APPLE MAC USERS -- Apple's Superdrive will probably NOT be
upgradable with the Pioneer Firmware, but you will need to check with Apple
to find out. Also, Pioneer may know about that issue, since they are the
ones doing the testing and re-writing of the upgraded firmware for users to
download.
