ANyone else out there trying to run mythtv0.19 on XOrg 7.0? (SPecifically in 
my case with the ATI DRI drivers).

Playback in mythtv is start/stop. Video is like 1 frame every 3-4 seconds.

sounds pause. (i.e. video frame refresh as sound starts again).

Logging with -v all results in

Anyone out there understand why this happens? I think it started immediately 
after I upgraded X last friday from 6.8.2 to 7.0. However mplayer, xine etc 
all still work fine. Including on myth recordings so it looks like some sort 
of interraction between myth & X, except that the logs would tend to indicate 
it's audio based... Ho hum...
