OK, I just hooked up my new HTIAB and my DVD's sound great, but the problem is nothing else does. I thought that If I put my stereo or TV into the reciever I'd get some nice 'psudo-surround' out of all 5 speakers and the Sub. Needless to say, I've been dissappointed. With audio from analog souces, only the rear two speakers are active. Is there anything I can do? Is this just my system (Sony HT 1700D), or are all Home Theaters like that?
