No sound from HD DVD to Marantz SR-6400
Just hooked up my new Toshiba A3 HD DVD player using HDMI to DVI to my 65" Mitsubishi TV that only has DVI and component video. So I bought the Optical audio line to run from my Toshiba HD DVD to my Marantz SR-6400 receiver so I could hear the best quality audio through it to my 5.1 speaker system. Problem is I don't get any sound at all, only video. Any suggestions?
