You HAVE TO slect a lineup FIRST. That is how SD knows what channels you 
can conceivably receive with a really good antenna. (The change to ATSC 
resulted in a major change in the number of channels which anyone 
possibly *could* get.)

You have to select lineups in accordance with the tuner type and 
reception capabilities. I have 3 lineups: one actually designated as a 
Youngstown NY zipcode, for US and some Canadian OTS (ATSC) channels, 
another using a Toronto downtown postal code, for Toronto OTS channels, 
and another using Mississauga for Rogers Cable. I need 2 OTS channels 
because the line-of-sight to the respective transmitters is 89 degrees 
apart. So 2 antennas, and 2 (HDHR) tuners.

Each lineup has a bunch of channels which I might possibly get with a 
bigger antenna, so those are marked 'off'. Did it once, some years ago!

Not difficult, just tedious.
