 I have 2 HD tuners and one analog device with 2 inputs (coax & composite).
 The analog coax input was recording a scheduled show.  Chose to watch Live
 TV in the frontend and instead of it falling back to the first available
 device (in this case, one of the HD tuner inputs) it tried to use the
 analog tuner, which temporarily interrupted the in-progress recording.
 When it couldn't, as the device was busy, the frontend got lost and hung,
 forcing me to manually kill it.

 This feature had always worked in prior versions.  I'm now running
 0.24.1-20-fixes.  The frontend log shows this repeated:

 address

 The backend log shows this, also repeated while the frontend is trying:
