Setting up samsung home theater?

i just bought Samsung home theater set Ht-Z320 for $250 and i started to st it up when i realized that all the speakers connect to the dvd player, problem is the dvd player dosen't play blueray and i have a blue ray player which i use, i have a stereo amplifier or w/e it's called but it dosen't work with the samsung speakers, is there anyway around this without spending alot of money? maybey somehow connect the samsung dvd player to the blueray so the speakers play the sound of the blueray player, or something, any hlp would b appreciated
