I have bought a Phillips 6 speaker system with a DVD player combined. I need to reconnect these speakers to a blu-ray player. Altogether there are 2 standing tallboy speakers, 1 large sub woofer, 2 small speakers, and a bar speaker. The Home Cinema system was bought as a whole and need to disconnect it from the DVD player it came with and plug it into a blu-ray play, how can i do this, help please.
