I'm getting choppy dvd playback with this new Toshiba 16x dvd-rom and a ATI rage fury pro video card. I'm wondering if it has anything to do with the Toshiba only having 128k cache compaired to others that have 512k cache? I'm using power dvd player 3.0. I've also tried using ATI's dvd software and it's the same problem. I also have a Duron 700 for my processor.
