Public bug reported:

Binary package hint: mythtv

Karmic Koala, mythtv 0.22.0+fixes22594-0ubuntu1

Expect: when turning "Sync to OpenGl" on in the Output settings menu,
output is as good as in jaunty i.e. no video tearing whatsoever with
this onboard GeForce 8300...

Result: with open-gl-sync:
2009-11-01 20:32:49.284 Frame Number Query reported error: Bad Context
Video is not playing smooth, problable 80% frames are dropped

Without open-gl-sync:
Video tears badly when cam is moved etc.

Settings in Nvidia-Tool "Sync to Vblank  .." -> on for xv and opengl.

Big regression from jaunty.

** Affects: mythtv (Ubuntu)
