How do you get your surround sound to work with DVD and Satellite system?

We got a Curtis surround sound system(not wireless) that came with a sub-woofer, 5 small speakers and a DVD/Blu-Ray player today. We have the speakers hooked up to the DVD player but don’t know what we need to use to hook it to the satellite so it works on both.
We have two extra cables and we are not sure where to use them or even if we have to… the cables are the ones usually plugged in for the audio (the red and white ended cords).
