I'm getting an error from mencoder when attempting to
transcode.  The error is at the end of this block of

You have certified that your video stream does not
contain B frames.
REMEMBER: MEncoder's libavformat muxing is presently
broken and will generate
INCORRECT files in the presence of B frames. Moreover,
due to bugs MPlayer
will play these INCORRECT files as if nothing were
wrong!

OK, exit

Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.

Exiting...


Where should I start to investigate/resolve this?
