while trying to set up this dvd player (Lenoxx DVD-2800) I discovered that the output jacks on the rear are not just as simple as Av cable Red/White/Yellow. I am assuming that the outputs are dedicated surround as dependant on what is plugged into where, various sound is eliminated from the dvd. How do I set the dvd player to just operate from basic 3 cable AV and to what outputs do I utilise from the rear?
