for MPEG-1 you don't actually need mpeg_encode. Most Linux/Mac systems
come with the NetPBM tools which include the "ppmtompeg" program.

And "ppmtompeg" is just "mpeg_encode" with bug fixes. just make a
symlink. Debian's version works fine.  See the r.out.mpeg module.


MPEG-1 is fairly crummy quality wise; as Dylan noted, mpeg2encode creates
nicer MPEG-2 movies. You can use mplayer's mencode to create even nicer
MPEG-4 movies.  http://www.mplayerhq.hu


Note that anything newer than MPEG-1 probably has patent liability
issues to think about.
