I've used several programs in an attempt to backup my DVD collection. ALL the finalised burnt CD's to-date have, without fail, some glitch in them!!! ??? I have used mainly Nero (full version) to burn, but have also tried other burn programs with the same results. The files play back fine and without any glitches on my PC, but after burning onto a CD, some flaw, however minor crops up in EVERY ONE ... ??? Any pointers or suggestions guys???
