[mythtv] SVN[8675] live TV stops at program end

I watched live TV today (NFL AFC Championship Game) for the first time
in a long time.

The live TV basically "stopped" at the end of the pre-game show (3pm)
and the end of the game (6:30pm) - the only two program "breaks".
There was no crash or anything; everything just stopped, as if the
backend decided to stop recording data and sending it to the frontend.
Pressing ESC and re-entering live TV brought me back to live TV.

Snippets of the backend logs (run-time flags happened to be -v
record,commflag at the time) are attached for the two time periods
mentioned above. The frontend log snippets from those time periods are
also attached.

The backend HTTP status shows that the backend still believes it's
recording stuff, but the frontend is receiving anything.

The system is an HD-3000-only system, recording OTA.
