Well my first attempts at HD on this box haven't been successful. There is a 
noticeable lag in playing back HD content, CPU runs at about 80%. Of course 
this is a 768p screen so the frontend needs to downscale the output.

Would you share your xorg.conf? I'd like to see what you've done.

HDMI audio also isn't working. I just get noise. Gotta carefully go through 
the various wiki pages on digital audio.
