It's a long time since I did a full scan but as far as I can remember
I had a similar problem. I think I went through a process something
like this:

Delete all the channels.
Using the frequencies figure out which transports are from the
transmitter I want and delete all the others.
Do an existing transports scan.

Of course if an existing transports scan causes mythtv-setup to crash
I guess this isn't going to help you much. I guess you could do it in
a more refined way and only delete the channels that come from
transports that you don't want and skip the final step.
