[mythtv-users] Coincidentally broken tuner or something else?

[Raymond Norton]

I am running .24 on a Zotac box with an HVR-1950 usb tuner  on Linux 
Mint 12. This setup has been pretty rock solid, but is not working well 
today.

The other day I upgraded all packages via apt. After that I started 
getting errors in Mythbackend, saying files should be local, but can't 
be found. Researching the error, I found it was related to the tuner. I 
set the capture cards up again and it seemed to be working, but today I 
am finding it will only tune to very few channels. The rest I get no 
lock, or partial locks, with myth popups telling me it should have 
locked in by now.

The tuner has two sides, but I have only configured digital to tune in 
HD over the air

Can anything in myth affect how the tuner works, or am I dealing with a 
failing tuner. Is there a way of testing what might be the problem?
