Has anyone heard of certain DVD's not playing the DTS tracks correctly? Let me explain-the new Josh Groban PBS Concert DVD has a DTS track and a Dolby 5.1 track. On either one, the center channel is dead. The vocals come out of the right front channel. I played a different DVD to verify that it was not my system and it worked fine. So I tried the Josh Groban DVD again in a different player and it did the same thing. I wish I had another receiver to try it on. Is it possible that my Onkyo TS-898 is decoding it incorrectly? Any one else with this DVD?
