Code: I have been using my Marantz SR5200 receiver and 5.1 Paradigm speakers with a Panasonic DVD player for past several years. With the optical audio output of the DVD player connected to the receiver's optical audio input, I was able to hear good surround sound from all speakers. Now I have upgraded to Samsung BD-P1600 bluray player and the optical audio output of bluray player is connected to receiver's optical audio input. When I play a DVD movie in the bluray player and the player is setup to output a PCM signal, I hear only stereo sound from the front 2 speakers. When I change the blueray player setup to output bitstream (reencoded), I get surround sound, but the volume from the speakers is almost inaudible. Is the Marantz receiver not compatible with the blueray player? If not, how can I correct this?
