Hi can someone please advise me how to (in very plain non technical language) how to wire up the following LG products together with an Xbox 360 as I have no idea, I don,t know where to start. I don,t know which leads have to go where and if I need new leads. The products are 42LF7700 (TV), HRT403DA (HDD with subwoofer and 3 speekers), BD370 (Blue-ray) and Xbox 360. Thanks Tracy
