[MEncoder-users] Mencoder and lots of duplicate frames / can't get video output

Hello list.

I compiled the latest version of MPlayer (against ffmpeg trunk) in
order to encode some videos using VFW codecs. The encoding process is
somewhat odd since I can't get any video on the output files.

Besides, when encoding, mencoder complains about 30ish duplicate
frames at a time. Any ideas on what's wrong?


Here's what an encoding session outputs:
