Newbie alert, newbie alert.. I'm on the market for a Home Theater receiver. I have a Sony KV32V40 Tv and a Sony DVPS300 DVD player. Both have S-video, optical cable, and RGY composite connections. How important is it that the receiver I buy, has an S-video connection ? (I'm looking at Denon AVR1403 and a Yamaha) Can someone give me a quick overview of how I should connect the DVD/TV/receiver together ? (ie. do I switch everything through the receiver, and if so, what are the best connections for video and sound ? thanks !
