This is in fact a problem.  In my initial version of this feature, 
mythfilldatabase left the channum alone for existing channels.  But then 
someone submitted a patch that updates channum for existing channels 
(ATSC or not), and did not take subchannels into account.  I submitted a 
patch which does this right for ATSC, but as you've seen this is not 
ideal behavior sometimes.

For right now, yes, you'll have to map _ on your remote in order to type 
channel numbers in live TV.  I think this is also a misfeature for 
people who have multiple providers combined into one MythTV system -- 
cable and satellite (e.g.) could easily both have a channel 12.

I'd like to hear from the person who submitted the patch to always 
update channum (Isaac had lost track of who it is) as to what problem 
this is solving, and maybe we can come up with a solution that doesn't 
kill people's hand edits.
