I've been seeing this too. I have two DVB-T cards in my backend. If
neither card is recording, I get this:-

2007-12-06 13:57:56.592 AutoExpire: Found max recording rate of 0 MB/min

not measure Bit Error Rate): Operation not supported
2007-12-06 14:05:51.113 DVBSignalMonitor(1)::constructor(5,Warning, can
not count Uncorrected Blocks): Operation not supported

If one card is recording, I get this:-

2007-12-06 14:34:01.903 TVRec(5): Changing from None to RecordingOnly
2007-12-06 14:34:01.925 TVRec(5): HW Tuner: 5->5

2007-12-06 14:34:03.150 Started recording: As It Happened "Two Men in a
Trench - The Siege of Newark": channel 1003 on cardid 5, sourceid 1

and lastly if both cards are recording I get:-

2007-12-06 15:33:30.423 TVRec(4): Changing from None to WatchingLiveTV
2007-12-06 15:33:30.430 TVRec(4): HW Tuner: 4->4
2007-12-06 15:33:32.121 AutoExpire: Found max recording rate of 277 MB/min
2007-12-06 15:33:32.186 AutoExpire: CalcParams(): Required Free Space: 2.0
GB w/freq: 8 min

So it seems that if a card isn't recording, the DVB Signal monitor can't
see it, and it appears to have a zero bitrate.

I'm using SVN somewhere around R15025.

Cheers,

Jon
