[elrepo] Intel video on CentOS 6.4

[Andrey Zhunev]

How do I know that the correct video driver is loaded?

The reason for my question is the following lines in mythfrontend log:

CoreContext mythrender_opengl.cpp:66 (Create) - OpenGL: Could not determine whether Sync to VBlank is enabled.
CoreContext mythrender_opengl.cpp:142 (IsRecommendedRenderer) - OpenGL: OpenGL is using software rendering.

And VAAPI or OpenGL-based video playback ends up with a black screen.
Not sure if it's a mythtv misconfiguration, or something is wrong with
the video driver... I suspect the latter, but I'm out of ideas how I
could dig this further.
