ive had a got at setting it up and ive got the DVD player to work through every speaker but the TV only works through the center and the front two speakers. the back two sorround sound speakers only have a very small amount of noise comming from them when the TV is on. they surly should be as load as when a DVD or music CD is playing. ive got a TV, Video, NTL Digital and the home cinema box. at the minute ive got the home cinmea box connected the the TV via a scart cable, the NTL box is plugged into the TV via a scart cable and another scart cable comes from the NTL box and connects into the Video. have i connect this right to get all the speakers to work when the TV is on? also do i need any other cables other than the three scart cables? thank you in advance for your help.
