I think I agree... Is there a counter somewhere that could be used to
find out which frame in the GOP we are at?
Some options I can think of:
1) change code to not skip a B-frame if it is the second frame in a closed GOP
2) only skip B-frames if they directly follow the first I-frame of a non-closed GOP
3) (without really knowing what "broken link" means) only skip B-frames if "broken
link" is set
