[mythtv-users] Problem with Mythtv & QTE

Hi!
Thank you, it works now. But i had to load the matroxfb_maven module.
As far as i understood this, matroxfb_maven will prevent directfb from
controlling the TV-OUT. And this is bad, because i'm not able to use
mplayer. Maybe this happens also with Mythtv. I can't watch Livetv, it
gives me segmentation faults ;).
I think i'm going to use X.
Any suggestions?
