[mythtv] MythVideo unberably slow in high resolution, 100% cpu usage by X11.

I believe this is a bug in MythTV that's why I post on the dev list. Why
 on earth does myth take 100% cpu and still take around 2 seconds to
reach the next entry in any media list while using the opengl painter
sounds like an obvious bug or nasty design miss to me.

I didn't mention video sources as they are not relevant to the problem
the problem is that the frontend is unbearably slow while browsing any
kind of file, game list, video list, tv guide, video manager, you name
it. Regardless of the source type. This is clearly a problem with the
frontend.

When I say "scroll in the video list" I mean "scroll in the list of
videos" video as in DivX, XviD, whatever MythVideo.

I put the output from a mythfrontend -v playback run at:
http://zero-kelvin.org/pub/output
I didn't run any videos or games or anything just used the frontend
which still exhibited the unbearable slowness.

I tried and it had no effect what so ever
