The more I look, and the more I read, the more I'm confused. Here are some basic questions, help me if you can. A. Can a DVD with DTS send the discrete channels via the analogue phono outputs or does it have to go through the digital optical / coaxial connectors? I ask this because I just read a review of the Samsung DVD-811 - and maybe it's the way I read it - but it seems to suggest that DTS is via the optical and coaxial connections only. B. Anybody got any brief explanations of Dolby Pro Logic, Dolby Digital and DTS? I just want to get my thinking straight. Thanks in advance.
