[mythtv-users] Mythtv Internal Player and ATI Radeon DRI

When I use the internal player for whatever in MythtTV it works except that the blue and red channels are swapped (the sky looks red and the tomatos looks blue :-D )
When I use mplayer I don't have the problem. That's ok for watching videos and  DVDs but not for TV because we can't change the player.
I found that this problem is bound with the DRI (direct rendering) option of the ATI Radeon driver (official driver from ATI).
When I desactivate the DRI the colors are OK but then all the work is done by the CPU and it looks that it is not fast enough (sound not sync with picture, frames droped,...)

Does anyone have an idea/solution?

I've read somewhere that the internal player was based on mplayer and found in the mplayer change log that there was a very old fixed bug (Feb 1, 2001) about swapped red-blue
http://www.mplayerhq.hu/MPlayer/releases/ChangeLog-1.0rc1 Could this be the same?

There was also an other problem with mythvideo and the DRI option of the ATI Radeon driver: Crash of the frontend when we try to browse the the video list
This was solved by recompiling the sources with the --enable-symbol-visibility option. Thanks to Anduin Withers for this.
