I apologise for my total ignorance, I am pretty much new to home cinema and im sure this question will land me in the 'dunce' catergory but here goes anyway: on the back of my dvd player i have 4 different 'outs' to connect to my amplifier. digital, coaxial, video and the normal red and white. which should i be using? all of them? just one? what is the differance in the connections? as i said i apologise for the basic-ness of this question but the manual isn very clear at all. thankyou very much for any advice!
