Do not change your channel ID's. They are MythTV-internal, irrelevant,
and (most-importantly) not-user-editable values.
Just fix your XMLTV ID's. In mythtv-setup channel editor it's the 2nd
page or so.
Oh, and rescanning channels and mythtv-setup (with or without
--do-channel-updates (which you should really never use) and/or
--only-update-channels) will never change XMLTV ID's. So, the /only/
way (and the designed way) to change XMLTV ID is to edit it manually in
mythtv-setup or MythWeb channel editor.
