Which is the best way to hook the following components together: Denon 3803 reciever, zenith hd 520 and denon 1600 dvd? Is it better to have everything go through the denon reciever than to the plasma , or dvd and zenth directly to the plasma? If I go through the reciever what input would be better on the plasma 1 or 2 or would it make a difference?. thanks
