[mythtv] ATI Color issues

Ok, that worked, however now I don't get an on screen display.
Is this a known issue with this work around?
Also after I recompiled my sound is about 1 second behind the video, I
re-commented the line and compiled again but sound is still off.  I then
tried running the mythfrontend as root, but that didn't fix the sound.

So I guess my two questions now are how can I get the OSD to work, and
fix my sound delay.

Also does anyone have any details as to what is wrong with the ATI
driver?  I will be happy to contact them about it, but I would need to
know what is wrong.

Thanks for the help so far.
