Comment (by ignissport@…):

 It's definitely not the AMD cpu clock issue for me. I've tried that, along
 with everything else listed in the troubleshooting on the wiki
 (http://www.mythtv.org/wiki/VDPAU)

 After a lot of playing around, I can confirm that this stutter '''only'''
 occurs when I have TwinView enabled. I have two TVs; one on DVI running
 1080p at 60Hz, and the one on HDMI running 1080i at 60Hz. The TV OSD tells me
 60Hz, but xrandr tells me 50Hz, regardless of whether twinview is enabled
 or not. I don't think that's the problem though, at it still happens with
 TwinView enabled.
