I have a really crappy hookup to the Berkeley MPEG library that you're 
welcome to use.  It doesn't support sound, or fast-forward, or 
anything.  But, it'll give you a bitmap of every frame, so if you just need 
that then it works okay.  The, uh, "interface" is below (Image.t is just a 
bigarray wrapper you're welcome to have as well).
