No, it doesn't work like that. I'll give you my example: I get my signal from 
Hannington, near Basingstoke. That's in the BBC South/Meridian area, so I get 
those local channels. I also get *all* the national channels from there.

I can also get a signal from Oxford, which is /behind/ my directional aerial. 
That transmits BBC Midlands/Central (south) local channels. It also transmits 
*all* the national channels as well.

As I can also (!) get a signal from Crystal Palace - 60 miles away - I have to 
use the procedure I outlined to you in my original post in order to make sure I 
pick up the correct set of muxes, since the scanner starts at channel 21 and 
goes up to 69, creating entries as it finds muxes - which are all interleaved.

If you do the same, you'll result in /one/ complete set of channels from /one/ 
transmitter and that should be all you need.

I also have two tuners connected to this aerial. This means that I can record 
programs simultaneously on two muxes. Multirec allows me to record more than one 
program on any selected mux; if you need to record from different muxes you need 
more (physical) tuners. A tuner can only tune to one mux at any one time.
