Do you have a sample demonstrating this effect? Either the coded (wrong)
bitstream or a source file + settings to reproduce the problem?

Is this really _only_ happening with bvhq? Iirc, the cartoon mode doesn't add
any special optimizations for b-frames - in fact, it wasn't even meant for
using it with b-frames (at least I didn't test it much). Do you have a sample
clip for this problem? I suspect that probably some MBs are skipped in
b-frames, which shouldn't have been skipped - but you know, cartoon mode
rather aggressively forces the use of skip mode...
bye,
Michael
