Ok I just got this home theater in a box. I got everything hooked up. I used a digital coxial cable for the 5.1 and dts sound. But for some reason I can only get sound from dts. If I put on a dvd that only has 5.1 I get no sound! I'm ready to throw it out the window! I even tryed switching the audio on the dvd from 5.1 to dts, etc..
