I've just read this thread..

Could anyone tell me the exact difference betwee the 794 and the 797 ?
My local dealer is selling them with various connector interfaces. Does this imply one one controller can be used for one brand type ?

For example, if I want to control a Pionner Plasma media Receiver and a Denon AV receiver would I need two of the Xantech 794 and 797 ?
