What about disabling OpenGL sync (in frontend settings under Playback on 
the page "General playback"):

Enable OpenGL vertical sync for timing
If it is supported by your hardware/drivers, MythTV will use OpenGL 
vertical syncing for video timing, reducing frame jitter.

If using SVN head, you'll also have to make sure you use the QT painter 
(in frontend settings under Appearance):

Paint Engine
    Qt
    OpenGL
This selects what Myth uses to draw.  If you have decent hardware, 
select OpenGL. Changing this requires a restart.
