 I am using the following version: mythtv-0.25.2+fixes.20120802.46cab93
 My mythfrontend is getting stuck somewhere after failing to start livetv.
 I start watching livetv and get prompted that there is no signal on the
 current channel. Everything works there.
 When I change to another channel, I see these two lines on the terminal
 output:

 {{{
 2012-10-27 19:45:09.278505 E  TV: StartRecorder() -- timed out waiting for
 recorder to start
 2012-10-27 19:45:09.278519 E  TV: LiveTV not successfully started

 }}}

 GDB shows me this:
