OK, looks like I finally got it straightened out.  Tried Jelte's method
first.  For some reason the scanner thought those three channels were
encrypted.  However, I told it to accept them and their "unused"
transports anyway.  I still couldn't tune them, but at least this step got
the multiplex ID into the database.  After this, I deleted the duplicate
channels, made sure all of the fields in the new rows in the channel table
were populated correctly, and restarted everything.  I was now able to
tune the missing channels. :D  Went through the channel table and cleaned
up the oddball new chanid numbers, ran mythfilldatabase.  Everything looks
OK at this point  Keeping fingers crossed.  New DB backed up ;-)

Thanks all for the help.

I hope TWC doesn't pull this again for a while.
