[mythtv-users] Tuning oddness - errors in log - ivtv or mythtv?

I've hit this twice in the past two weeks, but quite suddenly, we will
have troubles watching tv (yes, every now and then, that option does
actually get used) because it thinks all of the tuners are in use.  In
looking at the system status, no tuners are in use.  With that said, I
don't know if it is silently NOT recording anything that is scheduled
because the tuners are all thought to be in use (is there a way to
determine this?).

The logs show:

This seems to happen to all of the tuners, one by one..  A restart of
mythbackend did not clear up this issue.  I ended up restarting the
entire backend, and it started working again.

Could this be an ivtv issue rather than a mythtv issue?
