You do the channel scan from within mythtvsetup and you're right, you
need to enter the frequency with the other data that you've already
found.

I think tzap creates a file called channels.conf, but it's not
necessarily the same file that mythtv refers to.  It does contain the
data that the mythtv channel scan uses though.

Look in here:

(search for tzap)

And apologies if there's a better way to find out the frequency, but
this was the way I did it.
