Hello all,
This has been a very frustrating problem for our library as well. Some DVD's
look like they've been used as coasters, yet they still play well in most
units. Others look almost pristine, yet have whole chapters that skip. One
problem I have come across that seems to be the result of players is a
pitting pattern in concentric rings that appears on the protective plastic
layer the laser reads through. Once the pitting becomes pronounced enough
you start to get playback problems. Cleaning alone does not seem to solve
this issue. I am close to buying a re-surfacing machine to see if I can
extend the life of some popular titles.
Thanks for reading my two cents' worth.
Val
