I have recently found that I am getting the above error and no matter what I google I cannot get a resolution. My TV tuners are two (2) HDHomeRuns and the problem has only surfaced over the last couple of days.

To troubleshoot the issue I have deleted all my inputs and channels, readded and rescanned, but alas the problem still persists. What is happening is that I can open LiveTV and it will tune to a channel, but as soon as I try to change the channel it drops with the aforementioned error. I have separate BE and FE.

Errors from the frontend log are:

Is this strictly a live TV problem or dos it generate empty ( zero bytes ) programed recordings?

I didn't have anything recording, but I have just started one and it is working fine.

Just a couple stabs in the dark here, but...
I feel like I once had an issue with live tv that appeared out of nowhere and it was due to the Quick Tuning being enabled for Live TV in the backend settings for input connections. I feel like that was any time I tuned to live TV, though.

I have also noticed that mythtv has some subtle differences when changing channels through the guide and typing in the channel number vs. using the channel up/down buttons. What I mean is that sometimes it will automatically switch to a preferred tuner when changing channels and other times it will remain on the tuner that it is currently using. You might consider playing around with that and also trying to change tuners from the menu while watching live tv to see if it still bombs out.

Sorry I don't have anything more helpful, but I understand your desperation and hope that this could shed at least a little more light on things.

Thanks for the suggestion Knappster, however changing from the guide has the same end result. Changing tuners works fine and they tune fine. The problem also presents at the end of a program and going to the next one.

I am going to post to Gossimar thread to tap their incredible brains, I will post back when I get it sorted.
