Finally going to go for this. I rang up Sky today and the guy told me the boxes have Dolby 5.1 out. When I asked whether it was Digital Co-Ax or Optical out he checked and said. "There's a pair of phono scokets and a co-axial socket". Am I right in assuming that all Sky Digibox only have 2Ch Dolby? I'm Still going to go for it, but I want to run the right cable to the Reciever. If it's 5.1 I'll sit the digibox in the HT rack, if it's 2.0 it'll go under the TV. I've heard there's very little between the boxes on performance, but what about user interface? Are they all exactly the same? Any tips on how to get a choice of Digibox? Cheers, Mark.
