IMHO, it's the video sources portion of 
http://www.gossamer-threads.com/lists/mythtv/users/264034#264034 .  It 
can be done differently (with mythfilldatabase using appropriate args to 
fix the analog video sources and a rescan to fix the digital source) if 
you're really careful and know what you're doing, but if you do anything 
wrong, you'll break MythTV.  And doing it the "complete" way only takes 
a couple of minutes, so I recommend (and use) the way that always 
works--the "complete" way, using the video sources portion of the linked 
post.  (Note, also, that I don't know what I'm doing when it comes to 
making these changes using the "overwrite the garbage and hope I don't 
leave anything behind approach.")

It's callsign.
