Having (briefly) looked at the FillDatabase code, I have to wonder why 
the above is necessary. Why not ensure that the file passed to the 
grabber is always correct by generating it on the fly? A temp file, 
filled with "channel " plus the result of a "select xmltvid from channel 
where sourceid=n and visible=1" (other options may apply, this is off 
the top of my head) will ensure you only pull in the exact list of 
channels you need for that source.

This means that, for the UK at least, one of the bigger sources of 
frustration would be removed - getting the database out of step with the 
<source>.xmltv file because one or other needed editing.

Now if we could only get the Channel_ids file to always match what the 
Radio Times website expects, and get the callsigns the same everywhere, 
we'd be set...

Obviously, the above may not apply outside the UK.
