HAPPY THANKSGIVING TO EVERYONE OUT THERE! I have a Panny RP91 dvd player, and I want to set it up to play dvd-audio discs. My current audio connection is a digital optical (toslink) cable to a Marantz SR8000 receiver. I'm under the assumption that to hear all the benefits of a dvd-audio disc that I also have to connect analaog rca plugs from dvd player to the receiver. I believe I need 6 plugs for my 5 speakers and 1 subwoofer. Is this correct? I can play a dvd-audio disc with DTS surround sound on my current setup, but I won't hear the added effects (higher frequencies?) that make the disc dvd-audio. Is this also correct? Assuming the above info. is correct, do I also have to make setup menu changes on both the dvd player and the receiver in order to hear the full dvd-audio benefits? I was reading on this forum and in my dvd manual that you have to change the settings for digital audio output and pcm down conversion. It would be helpful if someone could go over ALL the dvd and receiver setup changes that are necessary for dvd-audio playback. It seems like a lot of effort to make these changes every time you want to play dvds and cds that are of different formats. Is it worth the effort? Should I continue to play regular dvds and music cds through my current digital optical connection and my current menu setup or the new setup for the dvd-audio?
