This will allow you burn movies onto VideoCD discs, or stream them to a MediaMVP device if your server isn't fast enough to transcode the data. I use it for the latter.

The command line:

ffmpeg.exe -i original.avi -target pal-dvd -b 6000 -aspect 4:3 -s 720x576 -acodec mp2 -ab 224 -ac 2 -mbd 2 -sameq -async 1 -y converted.mpg

EDIT: I now use the -sameq option to improve the render quality significantly.
