I believe the recording rules use the callsign, not the chanid or channum
or xmltvid.

Basically the chanid is stored with the recorded program, and deleting the
video source loses that link. If you delete ALL video sources, then
re-creating the video source is likely to re-use chanids and they may not
be the same as before. This matters to me because I have a number of movies
that I've recorded on "normal" channels and I wrote a script which tells me
when the movies are re-airing on comm free channels so I can schedule them
to re-record. If myth had stored the xmltvid or even the callsign with the
recording it could have a chance of matching them up after re-creating
video sources but that's not how it's set up, so it's left with broken
foreign keys.

So matching chanid's *exactly* what you want to do. You want to re-use the
