Comment 2 for bug 293840

Marillat's repository has xvid, and I think while we continue to sync that it's in our best interest to enable xvid support.

While ffmpeg does have a built in MPEG-4 ASP encoder that is the same codec as "xvid", the general experience is that:

(1) By default the encoding quality is significantly worse than xvid's default [doom9 codec shootouts]
(2) Once you configure ffmpeg mpeg4 to match xvid's quality, the encode time shoots up dramatically.

There's also silly things here and there like cartoon mode for encoding more statically colored content, etc.
