hey all - i tried to play a dvd on my system (2.53 p4, 128m video, 512, etc) and it looked horrible. now i could have sworn i tried it when i first put it together and i don't remember it looking this way. the picture is very dark and somewhat "jittery". it's not really pixellated, but the picture literally shakes. i'm using power dvd software and have verified that all the settings are (i think) correct. the only thing i can think of is somewhat recently my drivers for both my cd-roms...disappeared. i went into device manager and it couldn't find them. i was able to add them back in easily enough. there are no updated drivers on the manufactuers website. my dvd drive is some generic sony model...i can get the exact model number if you think it will help. any ideas? thx!
