Comment (by ami_stuff):

 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
