Hi Didde,

I had the same problem, MythTV really didn't do anything it seemed, the 
ivtvctl --get-freq never changed. I fixed it by instructing mythtv to use an 
external channel changing program and I then wrote this program to run 
ptune.pl and this worked like a charm
Probably we both failed to see a point, but as a dirty solution it might help 
you.

here is my external program
$cat /usr/local/bin/mythchannelchange
ptune.pl --freqtable custom -c $1 2>&1 >>/tmp/chan

Hope this helps,

Greetings
