Hi I have a samsung 40 inch Tv with Sky plus soon to become Sky HD, with a home cinema surround sound system, everything is working fine at the moment.I have my Sky plus box connected to my surround sound via a optical cable. Does anyone know if I get a Blu ray player will I be able to connect to the Tv as normal with HDMI, and to get surround sound 5.1 will I need to connect via a optical swithing box between the blu ray and surround sound. I will need the switching box as my DVD/home cinema system only has one optical output
