I'd start back at a know state, and work up from there. So :

clear out your channels.
do the setup scan - This should give you all the channels in the db with
the correct logical channel numbers.
exit setup and make sure that works. (do not run mythfilldb at this

Once that's going, go back and fill in the xmltvids for the channels and
use mythfilldb. (We don't have a merge feature yet unfortunately) ( Or
just use the built in EIT DVB stuff, which does work in the UK, not sure
if this option is built into the rpms you're using though)
