You can re-set the starting channel by poking the cardinput table.

Open a console window (or ssh to the myth box) and use:

#/bin/bash
#  re-set-channel
#  Tuner='5'
#  Channel='43.1' or '105'
#
echo "update cardinput set startchan = $Channel where cardid = $Tuner;" 
 > tempfile
echo "exit" >> tempfile
mysql -u mythtv -pmythtv mythconverg < tempfile
rm -f tempfile

Set Tuner and Channel to something you know works, and then use the 
channel editor in mythtv-setup. To delete a channel use 'D' for delete ( 
the use of which is not exactly made explicit!).

If you hang the system, use re-set-channel from the other window.

Note that you can change the channel numbering and callsign data in the 
channel editor so whatever you like.
