Our library has circulated a large collection of DVDs for three years
using 3M double security strips - with only minor playability problems
for our patrons. In the last couple of months, however, we've
experienced many returns on new and pristine DVDs (no scratches,
bubbles, etc) with patron reports that the DVD will not load or freezes
half way through. (To add to our perplexity, other DVD players will
play these same disks without incident !)=20
Since we have not changed our processing practices, we are wondering (a)
if the drives in newer DVD players are more sensitive or (b) has there
been a change in DVD formatting lately (copy-proofing?)=20
Have other DVD collections noticed the same recent problem?
Thanks
