MJPEG is a already lossy codec, so reencoding to a lossless codec would
make the file much LARGER, not smaller.

Nobody has come up with a scheme for MJPEG P-frames.  Anyone that needs
them uses MPEG-2, and even there, there's no software for lossless
modifications to the video that I'm aware of.

Never seen it.  Could have something to do with the ODML headers.   I
would look at the MPlayer output for clues.  Maybe some other file
format would work better.  Or you might just want to use -edl instead.
