Just adjusting the set-up for this as my Dad has had Sky+ installed. It has 2 digital inputs (1 no. co-ax and 1 no. optical). Sky+ has only optical out whereas his TV/DVD combo has both. So really it sorts itself out. TV works fine and the DD5.1 is detected when a disc is inserted. However the amp is only seeing a PCM input from the Sky+. Now we are unable to try the 5.1 as he is not subscribed to Movies, but my Denon at home detects a DD input even if the program is only being broadcast in what I presume must be 2.0. The sound is coming via the optical port, as it goes off when I unplug the cable. I have changed the output to DD on the services menu of the box and assigned the optical in to the relevant amp input. Is it right that the amp is only seeing a PCM input and thus that it works so diffeerently from my own amp ?
