[mythtv-users] Playback Profiles - OpenGL 1080i vs 720p

[Bob]

I'm using mythtv version 0.21.20080304-1 and have set-up a custom 
playback profile.  My TV is set to 1920x1080.  When I playback 1080i 
content using my 1080i profile with OpenGL it works as I expect.

However, when I playback 720p content, the low shows:

VideoOutputXv: Desired video renderer 'opengl' not available.
                         codec 'MPEG2' makes 'xv-blit,xshm,xlib,' 
available, using 'xv-blit' instead.

Any suggestions?
