An observation and comments...
Many here have stated that when cheap media is used, the disc often will fail to play and/or write all the way to the limits of the media (4.38 GB). Yet when good quality branded media is used, these errors are eliminated. I am confounded by this reported problem. I have used so-called "grade-A" media (Verbatum, Maxell, etc) and also some of the "cheap" media (Princo and DVDPro) and I have NEVER run into errors / freezes beyond 4 GB... I always burn to the maximum capacity and the discs are readable in my Standalone players and on my DVD-ROM drives just fine, all the way to the end of the disc. I have bunrned close to 200 DVD-Rs over a one-year time span, so it is not just the "luck of the draw" that I have not observed the freezes/lockups on cheap media.
Can someone please explain to me the HARDWARE reason why such read errors are likely / more observed in the "cheap" media? Is it because of increased C1/C2 errors or possibly because of differences in reflectivity of the data layer? Or is it a physical problem in the media itself (eg, defects in data layer toward the outer edge of the "cheap" discs)?
Any insight would be appreciated...
