I currently have:
1. Xbox 360
2. Sony Home Theatre: DAV-DZ590K
3. My Sky HDi
4. HDD recorder
Will this setup deliver the correct 5.1 surround sound to my Home theatre system? I think that it is working because when I play Xbox 360 (Modern warfare 2) I can hear the helicopter flying right around me for example. E.g., engine noise comes out the rear left speaker when the chopper is behind me, to the left in game. Is this proper 5.1 surround sound?
