Sky +HD compatable with hdmi???
hi, pretty new to all this stuff but really enjoying it. Just ordered sky +HD to work along side a 1080 plasma, blueray and home cinema system. On my present system, everything runs through amp (onkyo sr50 then a single lead to tv. will this be the case with sky (just a hdmi into the amp)? - i've heard that you need a optical something or other to get 5.1
also parents have same setup but with a soundbar through a sub/amp. what do they need
