Ok. Here's the problem:
With several desktop games (mainly Seirra & Atari titles) whenever there are videos played between stages of game play, the video chops amazingly bad. I'm talkin a 5sec jump every 20-30 seconds with only a moments worth of audio at a time. All the games that I have experienced this with have been retail versions and fully updated, most recently: Matrix - Path of Neo.
I've attempted everything that comes to mind, cleaning and installing latest drivers, checking for corrupt/missing system files, triple checking dxdiag, heck, I even tried Atari's customer service lol.
The games all run perfectly between cut scenes, but this certianly has me baffled.
