Hey everyone, Sorry if this is not the right place to post this: I just bought a Sony HT and it's all set up, except that it won't decode in 5.1 or DTS. In 5.1 it simply uses R L SW and it won't play anything in DTS at all. The coaxial is connected between the receiver and the DVD player and I ran a test tone so all the speakers are connected correctly. I don't know why it won't decode. Any help would be appreciated.
