I know exactly what this is.

This is a codec problem.

This is what happens when the wrong MPEG-4 codec decodes something that was encoded with a different (Usually when DivX decodes XviD or the reverse) Even if they SHOULD be universially compatable for decoding.

Go into VirtualDub or something, see what the video streams FourCC is and then see what FourCC is being used to actually decode it. You'll see they arn't congruent right there.

The same thing also happens when you have low memory while decoding the video (or during encoding since you also have to read from the file then) and as a consequence, B-frames and I-frames get messed up because the software can't read the reference points. You can see that a lot when you try seeking through any one of those crappy DivX 5 fansubs out there. Go back and forth a few minutes and you'll see it for sure.
