So I have one of the first batch of dvd burners made, SONY DRU500UL and I've been burning backups with NERO or DVD Decrypter for a some time. However, when using decrypter, 1x burnt games are unplayable. I've burnt some NERO as 4x (my maximum default) and they came out okay. But usually I stay with 2x (for backup movies as well) just because it seems like a safe number. However, I've been thinking about picking up that new dual layer sony burner and burning at higher speeds. Will the quality still be as good if I burn at 4x or 8x or should I still burn at 2x with a new burner? I'm concerned about longevity and risk of damaging reading lasers as well. Also, my DVD burner is having trouble reading and identifying inserted discs at all, is that a sign that I should get a new burner? Will that problem effect the quality of burns? Any help much appreciated.
