Evening All, I purchased a Sky+ package a few months ago and recently upgraded my surround amp to a Sony STR-D930 DTS/5.1 Amp. I have been using it with a Sony DVD player and an XBox via the optical connections no problems and the amp, set on AFD detects the sound mode (Prologic, Dolby Digital or DTS) and works fine, however when I am using the Sky+ system, it only detects the input as 48KHz Stereo. I have checked the inputs, although I am also connecting the RCA analogs, I have the amp set on the optical input (checked this by disconnecting the RCA connectors and verifying there was still audio). I thought this may have been because most programs are not in 5.1, but I found it odd when I purchased a box office movie, marked as DS (in the manual, this is apparently "Dolby Surround", but DD is marked as "Dolby Digital"). I am assuming that DS = prologic, but still my amp doesn't autodetect the input and I have to manually select the sound field. I usually go with Cinema Sound B, but none of the predefined surround effects product a good enough surround effect, especially on the rear speakers, in fact it sounds more stereo, just with the centre speaker in action Any ideas? Happy xmas !!
