damn, windows XP, seems like its full of bugs
While this statement is not untrue, the problems have less to do with bugs in general and more to do with the fact that xp likes to do things like thumbnailing what it decides are media directories, thumbnailing things in general, making little useless previews, etc.

It also has something to do with the fact that mpeg4 video encoding and decoding is not a "completed" or "perfect" thing. It's still in development and hasn't reached maturity yet. Someday the tools for mpeg4 are going to be as commonplace and as (relatively) bug free as the tools for zip compression, but that day is not here yet.
