[mythtv-users] System hangs when watching tv

[Sergio Bello]

Hi forum,
I've installed Mythtv 0.21 on a Debian Etch system. I thing everything 
is working fine (communications between frontend and backend, with 
mythconverg db, etc). I can schedule and make recordings, and preview 
them on the small screen that appears when you list recordings. But 
everytime I try to watch a recording or watch live tv, my system (the 
whole operating system) hangs, I can't use mouse nor keyboard and I have 
to reboot my machine. All I can see is a black screen. I've tried to 
change several mythbackend and mythfrontend parameters, but 
unsuccessfully. Maybe somebody have solved the same or a similar problem 
and can help me. Any idea would be very appreciated.
Thanks a lot
