[mythtv-users] 1st tuner on Nova-t 500 can't tune

[Ben Firshman]

Yes, restarting the backend fixes the problem for me. (l--) is  
displayed too. Sounds like a similar thing.

I have EIT enabled for the radio channels, but I have disabled the  
first tuner, so I've no idea which tuner it's using for EIT at the  
moment, presumably the second, but that works fine.

I get none of those messages you're getting, but I do have a lot of:

[440643.580000] DVB: frontend 0 frequency limits undefined - fix the  
driver

Is that anything to be worried about I wonder?
