In mythtv-setup, from the menu option 6 is channel editor. Inside the 
channel editor is a selector called "Video Source". In there you can 
left-arrow or right-arrow and select your source name. Once you have 
done that the channels for that source will be visible. Then to the 
right of the source name is a button called "Delete". If you click that 
button it asks if you are sure you want to delete all the channels. Does 
trhis not work? Is it slow in some way?

The idea was not to delete the source, but just to edit it and change 
the details from North America Schedules Direct to Mulitinational 
whichever one you are using. Then the video source would still be there.

I agree it is a very clunky process. I did the set up entirely from the 
command line. If you do it from inside mythtv-setup it also invokes a 
command line program with a clunky interface. The worst part is 
selecting the channels one at a time by answering yes or no to each one.

I ran it from a normal user id and then copied the .xmltv directory to 
the mythtv home directory. /etc/mythtv does not get used unless there is 
a link to it from /home/mythtv/.mythtv.

If there is something specific you are struggling with I can try to 
help. I wrote that wiki page based on my own experience but there are 
obviously different ways to do it.

Did you see David's response? He pointed out that some of the 
information in my first reply was incorrect.
