Sony Dvd 5 Disc Changer 2002 Question On Hooking Xbox 360 Up To My Surround Sound?

Question on hooking Xbox 360 up to my surround sound? - sony dvd 5 disc changer 2002

Can I use my Xbox 360 and HD Drive Xbox 360 movies to my Sony DVD player and surround sound. The unit surround sound is also a 5-DVD changer. I want to play my Xbox 360 to your speakers and can also view movies playing on my Xbox 360 over the speakers, if I have a surround sound through. If possible, how they are connected?
