Coming from a (tired!) non-US user living in a TV Nation where
callsigns are not used, this is exactly how I have come to understand
the purpose of callsign in MythTV from posts by bjm and empirically.
For scheduling purposes, treat all channels with the same callsign as
the same. For EPG display, treat all channels having the same callsign
AND channum the  same.

As I use the same listings data for common channels on all sources
(data from tv_grab_uk_rt) it seems obvious for my configuration that
any channel having the same xmltvid should also have the same
callsign, because to MythTV, the channels *are* identical, just on
different video sources. In the UK, we don't have the same
national/local affiliates/syndication differencees except for
news/weather, which is taken care of through the listings.
