Sorry for the top post. I and many others have this problem. I have done a
backtrace during the freeze and get the same results each time. The program
appears to be hung in __nanosleep_nocancel() in the tls library. I also
notice that most people report a tls IOBOUND error in the logs, these seem
to be related. I have tried to get some help on this but have had my last 3
requests for help ignored. Here is my gdb output.:

Subject: [mythtv-users] Error was encountered while displaying video.
If I leave my knoppmyth box running while I'm not watching it, I will
eventually
get the error "Error was encountered while displaying video".
I have not tried to narrow it down to happinging on certain channels, but
there
is a possability that the signal becomes weak or gets too much
interfierance.
Here is what I see in the myth backend log.

I have also begun re-starting mythfrontend using nohup so I can catch the
output
even when X get's tired of logging. Here is the output from mythfrontend.

If I select OK. I get kicked back to the menu and everything is fine. I
guess th
is messages is a new feature to deal with some of the instabilities of
mythfront
end or the plugins.
