[mythtv-users] Screen corruption with fglrx X driver

[Arthur Green]

I ran into a similar problem over the weekend while trying to build a 
new frontend/backend system on an Asus Pundit 2, which has a Radeon 
X1200 onboard. I'd installed the latest 8.512 RPMs from livna and found 
similar corruption in mythtv-setup and mythfrontend. I've just now 
removed 8.512 and installed 8.501 - the menus in mythfrontend now look 
fine. I'm still getting a doubled image in LiveTV, but the menu issue 
has been resolved.
