Heh.. I turned that on, but wasn't too sure of what I was doing.  Does 
that only take effect when you enable XvMC?

Another thing I am in the middle of trying is swapping the video feed 
from the STB to the PVR-150 card on the BE from coax-only to svideo+L/R 
audio.  I just tested that against livetv, and the picture quality 
definitely improved on the FE machine.  Next step is to see if that, 
plus the xorg.conf settings for 720p, plus enabling de-interlacing + 
Bob, make things better on the HD set when displaying SD.

(... after writing that paragraph, I feel like I am qualified to go back 
and work for US government facility.. they *love* acronyms..  My wife 
would read that and complain that it "all looks like Greek to me.")
