This seems to be intermittent, but wondered if anyone knows what it could be. Playing XVID 12bit plays ok, but 24 bit causes both players not to playback correctly. WMP has lines across the display with audio, DivX has no video and crackly audio. These are the codecs i have installed.

AC3-ACM decompressor

AC3 Filter

DivX Pro Codec

Xvid MPEG-4 Codec

I guess I probably don't even need all these, or do i.
