So I was able to figure out chedit2.pl and have been successfully editing
the database.
Once I get the database trimmed, what is the best way to have the channels
I have removed from the database not show in the guide?
Is there an option using mythfilldatabase?  Or do I now need to delete the
unused channels using mythweb or channel editor on the backend?

Thanks for all the help
