I Am looking at getting a Sony HT system fo my HDTV thru a vip722, Xbox, DVD, playstation2 and Wii. Right now the 722 uses hdmi,the dvd player uses component,xbox uses component, and the playstation/Wii uses the AV (they hook up to a switch) all to my TV. My 722, dvd, TV and xbox have optical outs. Do all these have to hook up to the HT system directly or can I just use the light coming from my TV and get 5.1 from everything hooked thru the TV. At first I thought I could, but after some research I think I was sadly mistaken. I was just looking for a simply setup without having to buy a bunch of new cables. My TV is a Samsung DLP with only 1 hdmi, 2 comp, 3av, 1dvi, and the standard coax stuff. Just point me in the right direction. There may be no way without going high dollar. Thanks.
