The difference is even larger than I thought... ffmpeg was decoding
the DV file and encoding the audio at the same time but I had mpeg2enc
reading a pre-staged .y4m file.

ffmpeg -i input.dv -vcodec mpeg2video -f mpeg -b 5000 -g 15 foo.mpg
then compare to
mpeg2enc -R 0 -b 5000 -4 3 -2 2 -o foo1.mpg < input.y4m
Have fun :)
At the moment my AMD system's booked solid for other encoding jobs,
be a couple days before I can run some tests on it. Hmmm, time to
fire up the dual P4 system and get it sync'd up on all the projects.
Maybe over the weekend.
Cheers,
