I am trying out a new receiver a friend of mine might sell me but I am having trouble with it. I thought I hooked it up correctly but I couldn't get the surround to work on anything but my DVD player. Even the dvd player would not play through the dts signal only dolby surround. I don't know if I did something wrong. Another problem is that I don't have a separate powered subwoofer. My current one connects to the current receiver I have which happens to be dolby surround not digital. Any help would be much appreciated. I'm wondering if I need different jacks for my audio.
