Some error messages in mythbackend I'm seeing are:

2014-10-03 16:25:17.471 ChannelBase(1): IsTunable(MPEG2TS,731) Failed to 
find channel in DB on input
  '1'
2014-10-03 16:25:17.523 ChannelBase(1) Error: Setting start channel 
'731' failed,
                         and we failed to find any suitible channels on 
any input.
I'm also seeing:

2014-10-03 16:25:25.472 HDHRSH(1310D391-0) Error: UpdateFilters called 
in wrong tune mode

But I think that's on all the recordings so I don't think that's the 
problem.

Some things I've tried:

I updated the HDHR firmware to the latest 20140604 version. That of 
course means a reboot.

With that DB error message, I deleted and re-added channel 731 in case 
there was some database error.

But no luck. Still get a channel change error.

And no, nothing unusual in the HDHR log:

	20141003-23:14:18 CableCARD: Tuner2: vchannel 731 (363MHz-5029) access = subscribed

But that message *may* have been from using the command-line tool. There are similar messages as I was
testing the surrounding successful channels in live TV.
