Yes, all files which suffer from choppy playback trigger also a

[mpeg4 @ 0x7fc2cd2758c0]Invalid and inefficient vfw-avi packed B frames
detected

message in the MPlayer console output. Unfortunately, I have managed to
identify only a single video (Xvid encoded) which didn't show this
warning and I can't confirm that all videos which show the warning
necessarily exhibit the choppy playback issue.

Please see the attached log from an affected video. The MPlayer was 
built with your "ensure we exit decode loop" patch to ffmpeg applied, 
otherwise the log would have been full of "marker does not match f_code" 
messages.

Thanks,
