Hi all I am still new to this so please just let me know if I have posted this completely wrong and I will try to correct it. Right onto what this is about. I have just bought myself a Yamaha RX-V671 av recover with a set of q acoustic speakers. I now am wondering how I got about connecting it to my tv and accessories. I am trying to connect and Xbox 360 slim a ps3 slim and sky+ HD Box to the recover and also my tv I know to connect them all to the receiver via hdmi and then one hdmi cable from receiver to tv. just wondering if I need to connect any optical cables if so where thanks very much.
