Actually I think I fixed it now. Can't really confirm because I never 
saw the bug in action, but my code was reducing fcode to minimum without 
looking at gmc's average vector. This vector is clipped according to 
fcode and it used for future prediction (also in bframe's direct mode), 
so - at least in theory - I was doing a wrong thing.

I commited the fix some days ago.
