I have both the optical and analog outputs from my DVD player to my reciever. This has been bothering me for awhile, but if something a DVD only has 2.0 Digital sound, is it better to leave it as such or to switch my reciever to Pro-Logic to get surround? What I mean is, if I leave it on Video 1 with the optical connection, I only get digital 2.0. But if I switch to Aux with my analog connection, then I get Dolby Pro Logic Surrond. I guess the heart of my question is: when using my analog connection, does the DVD support dolby pro-logic surrond in analog, with specific forward and rear stage directionality, or is it a trick of my reciever that just equally distributes what's really 2.0 sound into all the speakers? This is bothering me because I don't like to loss in sound quality I get from optical to analog, but at the same time, I'd rather take poorer quality supported surrond sound than 2.0. Maybe its just my mind playing tricks on me, but I keep thinking I hear rear directionality in Pro-Logic, whereas that obviously isn't happening in 2.0. Any help would be greatly appreciated.
