For digital sources, since there's typically additional (manual) 
configuration required or channels may be encrypted, mythfilldatabase 
does /not/ automatically add the channels.  You have to force it to do 
so with "--do-channel-updates".

xmltvid, but that's irrelevant to this issue

digital: always deletes unless you say, "Trust me, mythfilldatabase, I'm 
the user; I know what I'm doing."  (i.e. "--do-channel-updates").

analog: only deletes if you specify the command-line argument 
"--remove-new-channels" (which is great for cable/satellite users whose 
subscriptions don't change--i.e. even though DISH added a new local 
channel from North Nowhere, Montana and TMS automatically adds it to all 
DISH lineups, Myth knows not to use it (unless you run mfdb again 
without "--remove-new-channels")
