I have been backing up dvds for quite some time now using Prodisc and Ritek dvd-r 4x media. I normally create a stick on label with "Memorex Express It" but have been having problems with some of my backups not playing or pixelating and stopping during playback. Peel off the label and no more problems. I have tried the problem discs in two different home players and my ps2 with the same problems. I like having the labels on but if the dvds won't play then they're useless. Anybody else have this problem or have an opinion regarding using labels?
