I'm way out of my depth. How do I connect the above three. At the moment I watch DVD's using my Z2 attached to my PC. Sound from the speakers and picture brilliant. (should I use the DVI output from my pc - is it worth spending the money on the cable?). How best to connect it to sky plus, and where on earth will the sound come from. I'm beginning to fear I may need to buy an amp. Any advice appreciated, I am clueless. I have a Radeon pro 9800 graphics card and some sort of creative audigy software, although this may not be relevant. Thanks.
