My painter engine is set to Auto. For some reason, it doesn't want to
stick to OpenGL - I see the following lines in the log:

CoreContext mythmainwindow.cpp:1020 (Init) - Trying the OpenGL painter
CoreContext mythrender_opengl.cpp:66 (Create) - OpenGL: Could not determine whether Sync to VBlank is enabled.
CoreContext mythrender_opengl.cpp:139 (IsRecommendedRenderer) - OpenGL: OpenGL is using software rendering.
CoreContext mythmainwindow.cpp:1039 (Init) - OpenGL painter not recommended with this system's hardware/drivers. Falling back to Qt painter.


Whenever I choose 'VAAPI Normal', I get an error 'Failed to initialize
video output' when playing any video.
The log for 'VAAPI Normal' is here: http://pastebin.com/raw.php?i=M3MGRUNr
