Just got my x box. I want to hook it up to the component input on the back of my tv. What all do I need to do that? Do I need the hd pak? I can't use the cables (red,white,yellow)that came with it in my component input can I? If I buy the hd pak Do I also need to buy a set of component cables? Is it ok to buy a used pak for $9 cheaper? What sound cables do I need? Sorry about all the questions just want to do it right. Thanks.
