TVheadend using HDHomeRun ATSC continuously when idle

TVheadend revision d66746ca 12/15/2011 10:34 pm
HDHomeRun ATSC, using dvbhdhomerun kernel drivers
Disabled options: "Autodetect muxes", "Idle scanning", "Monitor signal quality", "Write full DVB MUX to disk", and "EIT" for all services
Problem:
When TVheadend is idle (no recordings or video streams), it
(1) continuously starts and stops feeds, of PIDs 0x0, 0x1, and 0x1FFB, which I believe is a request for EIT
(2) continuously requests signal quality, as seen in dvbhdhomerun.log: "FE_READ_STATUS sym qual: 0" messages when idle or "FE_READ_STATUS sym qual: 64 FE_READ_SIGNAL_STRENGTH strength: 52 sym qual: 64 sig to noise:64" when receiving video
(3) spontaneously starts video streams to TVheadend, indicated by tuner-in-use LED on HDHomeRun and "FE_READ_STATUS sym qual: 64 FE_READ_SIGNAL_STRENGTH strength: 52 sym qual: 64 sig to noise:64" messages in dvbhdhomerun.log
As mentioned above, idle scanning, monitor signal quality, and EITs are all disabled. Is this expected behavior for TVheadend or should a bug report be opened?
For those of you familiar with dvbhdhomerun logs, http://pastebin.com/PK1bXfkD is a link to a log for about 57minutes of activity. It includes a 6min recording near the beginning, which I initiated from the TVHeadend webpage 6min prior to the end of the program; so the start was manual and the stop was automated. The recording came from adapter1, while adapter0 went unused. The light on the front of the hdhomerun showed adapter1 in use and adapter0 unused. Then 20 min after the recording successfully completed, adapter0 spontaneously fired up and outputted data to TVheadend, and continued until the end of the log, when I terminated TVheadend (I don't know of a way to stop adapter0 manually, since no recording was occurring).
Any one else seeing this behavior?

Here is part of the debug log http://pastebin.com/f1vsUfPw The part near the end where the log saysP
"[DEBUG]:dvb: "647,028 kHz" on adapter "HDHomeRun ATSC0", status changed to No signal"
is where it began to stream video on the network. I let it run for a bit, all the while Adapter0 was in use, but then finally stopped tvheadend (^C)

I am also seeing this. Please post if there's a good workaround. Thank you!

Bug reported here: https://www.lonelycoder.com/redmine/issues/962 Apparently this is a known condition.
