It's actually called DivX ;) Yeah, the smiley's part of it. The name was a joke on the old DivX scheme.

They dropped the smiley years ago when divx4 came out.

(And the major difference between dvd-style mpeg4 and divx is that divx uses mp3 for audio instead of aac).

divx is a videocodec that has nothing to do with audio. You can put it together with audio and other stuff in containers like avi or matroska.
