I also have tearing video in MythTV using XV output, vlc (XV and vaapi) and mplayer (-vo xv and -vo vaapi). I'm using kernel 3.1-rc4, Xorg 1.11, Mesa 7.11, libdrm 2.4.26 and intel-xorg 2.16. The tearing happends without moving windows or doing anything in the GUI, just during normal playback in a window or fullscreen.
I'm using Debian Sid with gnome-shell from experimental on a Sandy Bridge i5-2400.
