Well, I'm watching 1080i right now and my cpu is at 86% for  
mythfrontend and 17% for Xorg. /proc/cpuinfo says I'm running at  
2211.339 MHz. I'm obviously not running XVMC. Standard library and  
linear deinterlacing. My video is set to 1920x1080 on an nVidia 6200.  
I imagine my high resolution is why the CPU is running so high.
