In my case both the correct and the incorrect channels actually work 
My digital TV sees both channels too and cuts horribly confused if I 
just run an auto tune.  I have to run a manual tune to get it sorted out.

So I could just arbitrarily choose either of the channels to keep and I 
made the decision that I would drop the signal coming from the back lobe 
of a low power infill transmitter (we have lots of deep valleys in 
Wellington) because of the possible but unlikely event of signal dropout 
in bad weather etc.

I knew which channels to keep by consulting public documents about 
frequencies in use at various transmitter sites.
