It looks like this problem have something to do with keyframes.
VirtualDub have an option to force keyframes every x frames:
Q_Best_1.avi - keyframes every 1 frame - decodes ok
Q_Best_15.avi - keyframes every 15 frames - decodes ok
Q_Best_20.avi - keyframes every 20 frames - corruption
Q_Best_50.avi - keyframes every 50 frames - corruption

The problem with bidiretion prediction starts to happen when I force keyframes every 4 frames or more, see attached files.

"quick compress" samples are fixed as well since some time, so only "bidirectional prediction" decoding is buggy
