i currently have the Philips DVP5960 Upscaling DVD player with HDMI connectivity. i also happen to have a Surround Sound Speker system with a Coaxial and Optical outputs at the back. the philips website tells me that the DVP5960 has "Analogue audio left / right out, Composite video (CVBS) output, HDMI output, Digital coaxial out, Component video out progressive, Scart" as rear connections. my questions is: what cable do i exacly need to maximise the audio (Dolby, DTS or otherwise) of my DVD player in order to connect to my surround system?
