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

[Mark Kendall]

John

I made a change for OpenGL 1.4 drivers. Playback should now work
regardless of whether OpenGL or OpenGL YV12 is used - though I suspect
on that system the non YV12 version will be faster.

Would be good to know if it works correctly.

Regards
Mark
