I agree with all that Mike has said here, but I suspect that even that 
may be making things more complicated than is necessary unless you 
really want to be able to get your signals from more than one 
transmitter - perhaps to have the option of two sets of regional 
programmes - and your aerial and location will permit this.

If your best choice of a single transmitter is obvious, I think you only 
need to input the frequency for _one_  of its multiplexes and tick the 
option to look for others that are linked to it; but you need to have 
deleted _all_ your dvb channels before you do this.

Good luck!
