I have the Pioneer DV-578a and the Yamaha RX-V750. I can play DVD Audio and DTS disc but I jut bought Journey greatest hits in SACD and it only plays threw my 2 front speakers. I select multi-channel on my receiver but only the 2 front speaker’s output sound. I check all of the settings for the Pioneer DVD player and made sure I correctly inserted the analog inputs of my Receiver. Can someone help me out; I am pretty new with this SACD stuff. Thanks
