If that's the case, something's either wrong with ffmpeg or the
parameters that nuvexport passes to it.  The main problem is that ffmpeg
keeps changing their commandline parameters so I can't keep up with it.

mencoder and ffmpeg use the *same* routines for doing the encoding, so
in this case it's just a matter of mencoder having some better defaults
that nuvexport isn't setting (because I don't know enough about video
encoding to know what they are).

The reason the mencoder isn't recommended by me (the author) is that I
could never get it working.  Other people seem to have no trouble, and
I'd love to see more options added to the mencoder export modes.
