[mythtv-users] TV broken after time away

[Damian]

Hello all,

I have just got back to the UK after being away for 4 months. My
Ubuntu/Mythbuntu system has been on all of that time and I have been
using it remotely. Since getting back, I have run all available updates
on the system and all seems to be working fine except for Mythbuntu's
Live TV. I don't seem to be able to lock onto a channel. Recordings that
have been made while I have been away seemed fine until the last couple
of weeks when they stopped working.

Can someone help me to debug the problem here? I want to get back into
the world as soon as possible after a big break from media.

I have tried re-scanning for channels, but still can't get though to
anything. What should I do next?

Cheers
Damian
