Hi Jonas,

   I use a modified copy of this mysql script -
http://www.mythtv.org/wiki/Database_editing_script. I have added my
"favourite" channels to the script to configure as required. The main
bit you are interested in however is the first line of SQL:

update channel set visible=0 ;

This configures all channels to be invisible, therefore you can then make
channels visible by adding the statement as below for each channel:

update channel set visible=1,channum=1,xmltvid="bbc1.bbc.co.uk" where
callsign="BBC ONE" ;

You can also add other general preferences to the first statement such as
whether to receive OTA schedule information.

Regards

Dave K.
