Here is a rather quick and dirty script *WHICH MESSES DIRECTLY WITH YOUR
DATABASE*. It re-sets all your tuners to a 'good' channel number. Exit
LiveTV and run from this from a console. I call it 'startchan-fix' The
dangerous lines have been commented out. If you cannot exit LiveTV then
you will have to kill the frontend, and then run the script before
re-starting the frontend.
Adjust as required for your user, password and mythtv database name.
However this script messes with your database and it may be dangerous to
your sanity or even the WAF score in your house. The dog may bark at you
and your hair may turn grey, if it has not already. YMMV UAYOR.

#mysql -u mythtv -pmythtv mythconverg < /var/tmp/startchanfix
#rm -f /var/tmp/startchanfix
