In layman's terms and i picked a transponder that has a variety of channels listed, So as an example tune to 11307 V 27500 which has the following channels:
Flava, Blissmas, Scuzz, Chart Show Dance, True Christmas, True Movies 2, Tiny Pop, Buz Muzik, Pop!, Tiny Pop +1 ,Kix!, The Vault, PopGirl, Wedding TV Asia, Chart Show TV ,Kix Power, True Entertainment, True Drama
So basically you can record any of the above 3 channels while watching a fourth but you cannot tune to a different transponder to watch a different channel just the ones on the current transponder you are on Only
