You can use mythtv-setup to edit the start channel for the input(s).

What is supposed to happen is you attempt to start Live TV and it's 
unable to tune a channel, it should pop up a dialog saying we should 
have gotten a lock by now (wording should probably be improved over 
current to make it a bit friendlier/less techy, too), then it offers you 
the chance to switch to a different channel.  This has been in and out 
of working order--probably more out than in--for quite some time, and 
the best approach would be to fix this.  That way, your wife or anyone 
else--including visitors--would be able to figure out what's going on 
and how to get to a working channel.
