Yes, same with max_bframes=1, almost the same positions (so it does not
depend on # of B-frames so far).
No, I', not doing dx50 compatability.

Yes, I did packed, because it was easier to implement into xvid_stat.c
I'll try without to see what happens. However, I don't use msfdam for
decoding because it does not compile on Linux. MoMuSys does compile, but
it crashes...

I just tested unpacked. It behaves differently (better) but after a while
strange things happen, too.
Well, I'll see...
