I have a pretty powerful computer running on 60GB HD, Athlon 2600+, and 512 ram memory, Plextor PX-708A DVDRW drive, Radeon 9700pro, 300W PS etc... When I first got a burner, it was great and never had a problem backing up any of my precious DVD movies from my collection, then one day it started freezing during encoding for some reason. For several months now I've been trying to figure out why encoding with DVD Shrink and then copying with Nero demo or DVD decrypter is freezing my computer. I've looked into everything from possible overheating, to calling DVD drive tech support to check if it's a registry problem, to trying different settings (dvd-5,dvd-9,custom etc..), to reformatting and reinstalling XP (then installing and running only Nero, Shrink and Decrypter to see if it still freezes), to rearranging the stacking order of my dvd and cd drives, to playing with "master" and "slave settings", to trying out a different MOBO and videocard, to trying many different DVD movies to back up, to rearranging RAM memory on the mobo, to reinstalling different versions of Nero, DVD Shrink and Decrypter. Once in a blue moon it will actually copy a DVD fine but then goes back to freezing again. Now I'm starting to wonder if something is wrong with the drive itself. Would buying a new DVDrw drive fix my problems? The Plextor drive seems to be ok, it watches dvds and plays cds without any problems. The encoding will usually freeze the entire computer at the same spot, but sometimes it actually gets further or not very far into encoding at all before freezing. I'm completely baffled, what the heck am I doing wrong?! Thank you.
