Thanks for all the helpful comments!

Lauri, I added: "TexturedVideo" "true" to xorg.conf and xvinfo sprang
to life! MythTV now renders fine on the whole. On the downside, I get
some really bad flickering intermittently with that option. Not a little
bit of tearing, but whole missing frames. And sometimes when I change
channels the whole display is out of whack, quitting out of LiveTV mode
and going back in usually fixes it.

I didn't install fglrx but I'm wondering if that migh help with the

Regardless, I'm in a much better boat now, just in time for the men's
finals at wimbledon =)

Thanks again, hive.
