When converting MJPEG .mov files to DVD-compatible MPEG2 files, I was 
faced with a similar problem.  The solution was a 2-step conversion:


VCODEC="vcodec=mpeg2video:aspect=4/3:vbitrate=6000:trell:nr=100"
mencoder \
     *.mov \
     -o ${FOO}.avi \
     -ovc lavc -lavcopts $VCODEC \
     -oac pcm -channels 1 -srate 8000

ffmpeg -i ${FOO}.avi -target ntsc-dvd ${FOO}-0.0.mpeg

This example is tuned to my specific circumstance, but should be 
adjustable to yours.
