ATI does not support XvMC, so you will not be able to use it as a
renderer with that GPU.
> 2. Opengl as a playback option lowers my cpu use, but crashes every time I exit playing anything. The crash is a segmentation fault. I don't know the history of opengl work in mythtv so I'm wondering would a bug report would generate sufficient interest?
Only if you a) provide a backtrace per the manual (Chapter 22) and
wiki debugging page, and b) are currently using trunk, as that code
has all been rewritten this cycle.
