That's just so I can preserve the AC3 5.1 audio. I'm not making videos
to burn to CD or distribute on the Internet, and I have a big filesystem
to keep them on.

I expermented a bit a while back and couldn't get THAT much of a size
reduction from six-channel vorbis, and I don't really want to use OGM as 
a container anyway.
