Strange one, possibly there is a lock on the frontend from previously 
run istance of Myth, couldnt be sure without more specifics.

Yeah I had to put a signal booster on my aerial, not the best solution 
because it just boosts a bad signal, but it works. I imagine digi-boxes 
have built-in signal boosters.

You could try setting them to auto and seeing if it picks the settings 
up. Below are settings for one Craigkelly multiplex:

Freq. 570 MHz
Bandwidth 8Mhz
Lp coderate 3/4
Hp coderate 3/4
Transmission Mode 2k
Guard Interval 1/32
Constellation QAM 16

And set the others to auto or none.

I had problems with scanning on the Craigkelly transmitter when I setup 
a friends Mythtv (I use Blackhill transmitter). I found that it got 
stuck in a loop scanning all the channels over and over. There should be 
information broadcast on each mulitplex frequency with information of 
the other multiplexes available. For some reason when scanning 
Craigkelly it doesnt know when it has found all the frequencies 
available and keeps rescanning them endlessly. YMMV.

If you have problems like this you can enter the multiplex information 
manaully then scan each multiplex individualy, I can give you the 
nessecary info on the multiplexes available from Craigkelly.

The channels.conf file goes in $HOME/.xine/ directory, depending on what 
user you are running it under.
