[mythtv] [mythtv-commits] Ticket #1648: Firewire Recorder missing signal monitor (get's stuck)

[Jim Westfall]

I tried it out.  Only issue I have run into is the power-on parts.

If the stb is off and I enter livetv it will do the following.

2006-12-09 13:16:50.849 TVRec(1): SetFlags(SignalMonitorRunning,) -> RunMainLoop,AskAllowRecording,SignalMoni

There also needs to be ~3 second sleep after issuing a power-on command.  
The stb will say its powered on but wont accept channel change commands 
for a few seconds.
