So, I did one final test. I implemented the greyscale OSD fix. It
fixed the greyscale OSD problem, and seems to have improved the problems
with staticy sound when the OSD is being displayed, but it does not
really fix the problem. With the OSD up, the frontend uses 60% CPU, and
Xorg uses about 35%. I guess XvMC and the OSD just don't work very well
together.
