This might not be relevant to you, since it sounds like you did a 
complete channel scan, but I recently needed to add a new OTA channel, 
but did not want to do a complete rescan.  I did not want to deal with 
fixing all of the channel numbers from underscores back to periods 
(there used to be a global option to configure this, but it was removed 
many versions back :-( ).

I use the mythtv-backend-setup application, and select the Channel 
Editor menu (#6 I think).  From there, I would select each tuner and 
enter the channel scan menu.  There are only a few choices there for 
scan types (full scan, or scan existing transport).  I wanted to choose 
the scan existing transport to only scan (rescan) one channel, but the 
"transport" did not already exist.  What I discovered was I could first 
select the edit transport menu and from there select the add new 
transport.  This allowed me to add a new transport, so it would show up 
on the scan UI as an existing transport and voila, it worked.
