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

[Jim Westfall]

seems this is the problem

2006-12-09 13:48:54.983 TVRec(1): Request: Program(no) channel() input() flags(LiveTV,)
2006-12-09 13:48:54.983 TVRec(1): HW Tuner: 1->1
2006-12-09 13:48:54.983 TVRec(1): ClearFlags(PENDINGACTIONS,) -> RunMainLoop,AskAllowRecording,
2006-12-09 13:48:55.000 ChannelBase(1): Input #1: 'MPEG2TS' schan(111) sourceid(1) ccid(1)
2006-12-09 13:48:55.000 ChannelBase(1): Current Input #1: 'MPEG2TS'
2006-12-09 13:48:55.000 FireDev(0:0): Requesting STB Power State (cmd: 0x1ffb27f)
2006-12-09 13:48:55.002 FireDev(0:0): STB Power State: Off (0xcffb260)
2006-12-09 13:48:55.002 FireChan(0:0), Warning: STB is turned off, must be on to set channel.

This causes LinuxFirewireChannel to short circuit and never call

    SetSIStandard("mpeg");
    SetCachedATSCInfo(QString("%1-1").arg(channel));
