Just use the default and then edit the config file (maybe something like 
~/.xmltvrc or ~/.xmltv/*) by hand to disable everything and then enable 
just the channels you want?

Change the channel numbers (using the channel editor in mythtv-setup or 
MythWeb).  They can be anything you want (but don't modify freqid--even 
though it may start out equal to channel number).

You need to put the XMLTV ID into the XMLTV ID field.  BBC1 is either 
the channel name or the callsign provided by your grabber.
