Okay, I'll try that:  start mythtv-setup, say "NO!" to bashing my card
settings, say "yes" to bashing my video sources, and then set up all
the video sources again.  This is a pretty big pain just because the
provider changed its channel numbers around.  Should myth "just
recover" from this if I instead wait a day?  Perhaps recovering only
for "next day" and "last day" as time marches on?  If so, maybe I'll
wait a day instead.

    No.  It's only useful for listings changes.

Right, but if things don't get reset when listings change without
running this, it seems like running it preemptively might make
sense---assuming it isn't doing a ton of work or reinitializing
things that shouldn't be reinitialized.  I'm not sure -what- it's
doing, frankly.
