You can use either a HDMI-DVI cable for the video, or a HDMI-HDMI cable with a HDMI-DVI adapter on the TV end. As I understand it, the Xbox360 elite comes with an optical audio out via an adapter which you get in the box, you would then simply get an optical cable to connect the adapter to your amp (assuming of course your amp is a surround sound amp, and you have a free optical input). Alternateively you can use the stereo audio out if you do not have a optical audio input on your amp.
