I back my movies up useing DvdShrink and burn them with Nero Burn on ty 8x media useing a BenQ 1640 burner with bslb firmware (booktype dvd-rom). Problem is about half or more of the backup copies will either hang on playback, have artifacts or missing scenes. I burn at 8x speed and my ripper is a Liteon 16P9S. The copys act the same when played back on the PC or Sony DVD player.
Any suggestions...... Hootal!
