You haven't really missed anything as there is currently no
straightforward way to match scanned DVB channels to XMLTV IDs,
although I am thinking about taking a stab at it.

As Michael suggests, the easiest way to correct your channels is to
use MythWeb and manually match up the channels with their relevant
XMLTV IDs. This is what I did a couple of years ago, and it works
perfectly once it is setup. I have also seen a few SQL scripts
floating around in the last few years which do the same thing, albeit
automatically, but I'm not sure how up to date these are now.

You may have read recent messages describing issues with the uk_rt
grabber (Radio Times) but the issues have always been corrected and
works well.
