Yeah, you really need the -mmx branch for conferencing. There are some 
decoder asm patches available as well, and I've been working on a 
parallel version recent for the Elphel people.

The ffmpeg and vxid implementations have seen a lot more optimization 
work than theora has. We're getting there, but working on encumbered 
codecs seems to be sexier...
