It means your video driver installation is broken or your card/driver 
doesn't properly support OpenGL.  And, since you're using a playback 
profile that uses the OpenGL renderer, it fails.  The proper fix is to 
fix your broken video drivers.  Otherwise, you can just change to the 
Slim Playback Profile group (in mythfrontend Utilities/Setup|Setup|TV 
Settings|Playback, 3rd screen).
