For some recordings I get a steady stream of log messages saying it's 3.0xxxxx frames behind and dropping but even if I pause and forward a frame at a time there's still no picture. Fast forwarding doesn't show anything either so I don't think it's because of frames being dropped to keep in sync with audio.

The OpenGL video renderer has had very little testing on intel
hardware. If you want to post the full output of mythfrontend -v
playback and glxinfo, I can try and take a look. My gut feeling is
that the hardware just isn't powerful enough, though you may be able
to force it into to trying a different approach.
