I had "VideoOverlay" "on" and "OpenGLOverlay" "off". I have fought with
fglrx installation before, so I'm well aware of what a beast it can be.
I was pretty sure that Xv worked fine without the kernel module, since
it does for both the "radeon" and "nv" drivers, so I may have skipped
getting the kernel module to work because I wasn't interested in OpenGL
at that point.

But, to be sure, I'll try fglrx again. It'll be an interesting data
point, but I really hope to avoid using anything proprietary for my
mythbox. I'll probably get a Radeon 9600 or something to use with the
radeon driver or perhaps an Nvidia card for use with "nv".
