Good example. When using a grabbers that fills these in,
it is only filled when the entry is first created. Once the
row exists, you can edit the callsign however you'd like and
the grabber doesn't care (if the grabber never fills callsign
then it certainly doesn't care if you change it ;-).

This was the problem with early attmpts to do channel matching
with xmltvid. You cannot change it or the grabber will barf.
As you saw in my "KVBC" example, the xmltvid did not match for
the same station and I couldn't do anything about it.

With callsigns, you could change WPVI-D to WPVI so that myth
can record a show on analog when the digital input is needed
for something else. On the other hand, I could decide that I
want to record The Apprentice in digital or not at all so I
can change 2123 to "KVBC-D" if that's what I want.

Yes, agreed.
