1. Does burning DVD with a label on effect the quality of burn ? 2. If Labels effect quality of burn is clear plastic preferable to paper? 3. While burn is in progress should you NOT do anything else on your computer like play solitaire, surf the web or print 4. Are there any differences between using +R or +RW other then the obvious RW re-write option and price differences? 5. Does the playing of backups (burned on internal computer quality DVD drives) on Home theater quality DVD players with progressive scan and deinterlacers with 3/2 pulldown etc present any issues of concern?
