Hi all,

I have been using MythTV for well over a decade now. Usually when I
have a problem I can figure it out via upgrading mythtv, this users
list, or reading the code a little. But I'm stumped now.

I've been using an HD HomeRun Prime with CableCard in Portland, OR, US
for years. Everything was working fine until sometime between January
1st at 4 PM PST and January 2nd at 11:35 PM PST (the last good
recording and first bad recording). I mention this in case anyone
knows that Portland's Comcast has changed how they broadcast stuff in
the time period.

The tuner now fails to "tune" to any channels. I get the following in
the backend log file:

(TuningSignalCheck) - TVRec[10]: See 'Tuning timeout' in mythtv-setup
for this input

The frontend likewise complains about not being able to "lock" the channel.

I upgraded to 0.28, but this didn't help anything. Any ideas what I
could try to figure this out?

Thanks!
