I have a pioneer dvd 563 a. I just bought the aerosmith SACD and it only plays in 2.0! I have no sub and no center and I get a weird feedback in the center channel. Now I just put in Beatoven and it plays in 5.1 but it still has that same feedback in the center. What am I doing wrong. This is the second pioneer dvd audio player that has done this. Is it maybe the cables Im using... im using car audio analog audio cables to send the signal. Would that do it? This is driving me crazy! I hope I dont have to get a new player. Becuase the next step is a yamaha or denon for alot more money.
