Yeah, there are a few more things I should do for those scripts.  I've 
gotten a request for fixing chanid's on recorded programs (i.e. when you 
do a partial restore and end up with differently-defined channels 
because you created a new video source without using the delete all 
video sources approach, or whatever, or even when you move to an area 
with different channel numbers).  However, I'm thinking about changing 
the way we do xmltvid backups (so they work from a "standard" backup, 
rather than an xmltvid backup) to make that addition easier.

Stuart Morgan was asking for a "duplicate settings to another host" 
functionality for Myth, and I considered putting that into the scripts, 
but can't decide whether we need a more "intelligent" settings manager 
(i.e. code in mythtv-setup/mythbackend/mythfrontend to allow settings 
management) that understands what settings are necessary.  For that or 
for the delete settings stuff, I need to better understand if any 
settings (other than the SGWeight* stuff) have "external" references or 
are referenced by other DB data).

Also, if the code goes in mythconverg_restore.pl, I might need to change 
the script name.  :)
