[mythtv] ubuntu ppa master: green screen (solved)

[Mark Kendall]

Thanks John,

I had a pre-conception/inkling of what the problem might be - but
certainly wasn't expecting to see OpenGL 1.4 :)

I'm slightly surprised that it works at all. I'll put some checks in
to ensure similar setups always fall back to a supported OpenGL video
profile.

Thanks again and regards
Mark
