Bought this new DVD/Surround Sound 5.1 and having trouble, not sure that I have all the proper cords(I have the yellow, white and red as one cord, and two(2) sets of red and white cords) How/where do I plug what cord to where? My logic would be: (a) DVD player to the TV then from the TV to the speakers, or... (b) from the TV to the DVD player to the speakers.. Both of which don't work,
