Hi, I just updated to the kernel 2.6.31.2-1 package in testing and my video playback in MythTV is now jumpy on all video methods (haven't tested any other programs). Also, the stretch options have no effect, the video is stretched to fill the entire screen no matter what (though the text that appears to tell me the stretch mode moves around the top-left area). It worked fine in 2.6.31.1 and a downgrade fixes the issue.

My video card is an Asus EAH3450 (ATI RV620 I think), so I think it might have something to do with the fact that ATI KMS was enabled in this version (though I didn't think it supported R600 & R700 cards)
This task depends upon

Reason for closing:  Not a bug
Additional comments about closing:  expected behavior with cards not yet kms supported.

Just to clarify, in MythTV all video output methods are jumpy (opengl, xlib, etc) and when I change the video image stretch options in xlib and xshm modes they have no effect.

Forgot to mention, using xf86-video-ati 6.12.2-2 video driver.

It doesn't support the r600. You could try disabling KMS and see if it helps.

Creating a file /etc/modprobe.d/radeon.conf containing "options radeon modeset=0" does fix the problem, thanks.

I was really against this option because it is enabled by default. Let's see how many more people get problems. Feel free to post "me too"'s to this bug report.

I had problems too, but I'm using catalyst driver (don't know if bugreport about it could be reported). fglrx module cannot be loaded (Operation not permitted). I had to append nomodeset option to kernel command line to have it loaded correctly.

Yes, this is related and probably even normal.
