[mythtv-users] ATI (I know, I know) Issues

[Paul Manning]

I've got That mainboard and I have XV working.  Like you, I experienced plenty of issues with Xvideo overlay, even tried going for openGL for a while but performance was no better.  So far I've got my best results with the 8.5 version of the catalyst drivers on Gutsy.  Not a big fan of envy as it just installs the same version of the ATI driver, not the latest.  Then again, as I'm using Gutsy, I have to run the legacy version on Envy and not NG so I'm not sure what the differences are there.

Like someone else has already stated, you need to ensure you have the options;

 Option      "VideoOverlay" "on"
 Option      "OpenGLOverlay" "off"

in your Xorg.conf.  Also, rather than check your myth logs to see if you have Xvideo working, just type xvinfo into a terminal.  If it says no adaptors, you still don't have it working.  If it responds with a heap of guff, then things are looking up for you.

Sorry to double post (last one had no useful info in it).
Are you using the RadeonHD drivers? Supposedly the x1250 is supported 
there, but that driver doesn't have XV support yet. Maybe just using 
radeon will help. For older ATI cards I had XV working using just radeon 
and didn't need fglrx.
