<br></blockquote></div><br>Brad, I am also outputting to a TV in 1080p and using kernel deint with nvidia 9629 (recent). I have looked at my cpu usage several times throughout the past: on 720p material I see 60-70% cpu usage; 1080i 70-80%, it might be your nvidia binary... I remember there was one nvidia release that shot CPU usage through the roof, I think it was in the 6000 series though. I update myth to SVN almost weekly, and I run aptitude/deselect almost monthly to update the rest of the software and stay on the sometimes painful cutting edge. :)
<br><br> Are you running a FC released kernel? I'm not sure it matters but I'm using one I built from <a href="http://kernel.org">kernel.org</a> currently, 2.6.19. It's setup with exactly the drivers and options that I need. Make sure you are using nvAGP, you have to disable the agpgart in your kernel config in order for the nvidia driver to enable it's own driver.
