The start channel is set in the input mapping screen in mythtv-setup.  Has 
been ever since the setup program existed.

Err, no, it doesn't.  The code to find the next channel (tv_rec.cpp, 
DoGetNextChannel()), simply uses > and < in a SQL query to get the next one.  
If you have non-numeric channel numbers, you need to set your 'Channel 
ordering' (first item in the General TV settings) to 'channel number 
(alpha)'.

mythfilldatabase doesn't do anything with the channum field, except fill it in 
when creating a channel.  You're quite free to change it to whatever you 
want, and in the case of HD channels, I'd assume most people would want to 
due to the lack of a _ key on most remotes.
