[mythtv-users] debugging faulty channel

[Matt Harrison]

I've got a channel on my setup which worked fine for a while, but 
recently it kills my setup. Trying to tune to this channel will hang my 
frontend, and without a lot of fiddling with the backend, forcing 
recordings in mythweb and crying in the corner, I cannot stop the 
frontend trying to re-tune to it when it comes back up and starting the 
loop all over again.

I'd rather fix the problem than bitch about the symptoms though. I am no 
expert with any of this and I cannot work out how to even effectively 
debug the problem.

The frontend logs will constantly report they are waiting for the 
buffer, while the backend seems to think the recording is finished 
instantly.

I've tried running the backend with debugging on but I can't get 
anything useful out of it, especially as I don't understand most of it. 
Also, a retune doesn't have any effect at all. Two copies of the channel 
appear with a scan (as with most channels for me) and both have the same 
problem.

I'm running 0.24-fixes on mythbuntu 11.04 (although the problem was the 
same with 0.23-fixes on 10.4).

I would be very grateful if someone could advise where I should look 
next to work out what the problem is.

Many thanks
