I've got a very odd problem with my 6500/225. it absolutley refuses to play Quake properly. the game will start, and it doesn't crash but after a random number of seconds the video stops updating, typically right about when the console is about to be pulled up and the demo starts playing in the background of the menu.

any ideas? i've updated the game to 1.09, and have quicktime 6.0.3 and gamesprockets 1.7.5. the only thing i couldn't find was an ATI driver update, anybody have any idea where i could get one? its really buggin me
