Decoding. My experience is that it's not very CPU intensive,  
especially when compared against High Profile H.264 at 1080p. That  
makes my fans speed up but not Theora.

I do alot of encoding but none of it live. The newer version does seem  
slower, although I haven't done any formal testing. Maybe there's  
something to be said for hardware acceleration. If you're up for it, I  
say go ahead. :)
