Thanks! Now, I have to see why XvMC just doesn't like me. I have a
6200TC, which seems to be supported (according to threads here), and
when enabled, I get the B&W OSD. But, unfortunately, no CPU usage
reduction -- still stuttering hard on the high-bandwidth HDTV that CBS
seems to be putting out.

If you have any input, I'd love to hear it. Thanks Mr. Lee.
