I have noticed a recent problem (also occurring with Fallout 3) - the in game videos play choppy. The lower half of the video is blocky and off sync with the rest of the video. This happens in all in game videos for Oblivion and Fallout 3. What's the deal?
Bink videos (.blk files) all play normally and with no choppiness in the RAD video tools player.
All drivers updated
Windows XP sp3
AMD 6 core Phenom
