My Panasonic DVD-RA60 DVD Audio/Video deck is connected digitally to my Onkyo TX-SR600 receiver via an optical cable AND I have a set of RCA cables connecting the DVD player's analog outputs to my TV set incase I just dont want to watch DVDs in surround; 99 percent of my time is spent watching DVD films in Dolby Digital or DTS. While this system has been up and running for awhile now, I just want to make sure I have the correct settings under the Panasonic's "ACTION" setup menu... Under "AUDIO" I have these choices: MULTICHANNEL or 2-CHANNEL: I have this set to 2 CHANNEL since I was told MULTICHANNEL in the DVD player's setup would only be used if I wasnt using the digital cable to the receiver but instead using the 5.1 analog cables...BUT, no matter what I set this on --- 2 channel or multichannel --- it does NOT affect the sound one way or the other; I have tried it both ways and nothing is affected when playing back multichannel DVDs. But what SHOULD it be on? PCM DOWNCONVERSION: YES OR NO: I am not even sure what this should be on at all; again, no matter if I have this setting on YES or NO, I STILL get multichannel DVD sound when playing back DVDs....and just to remind, I am connected through a digital optical cable to the receiver AND RCA connections to the TV set, so what should PCM Downconversion be on? DOLBY DIGITAL AND DTS are both set to BITSTREAM; I know this is correct. Now....on the RECEIVER...when I press the DVD input, and go under the Input Setup menu, I have selections for: DIGITAL FORMAT: I have set this to ALL, so it decodes whatever is coming into the receiver (DD, DTS, etc). MULTICHANNEL: YES OR NO: Now...what should THIS setting be on? Again, my manual for the Onkyo TX-SR600 seems to say that this should only be set to Yes if the receiver is connected to a DVD player using the 5.1 analog outputs and inputs; so I set this to NO because Im using a digital cable...is this right? And yet again, no matter what I choose --- yes or no --- I STILL get multichannel surround audio when playing DVDs. ANALOG/PCM SOURCE: There are settings here for Direct, Stereo, Surround, etc......what should this be on? I believe I have this on SURROUND so that way the receiver kicks Pro Logic II on for 2-channel Dolby Surround DVDs. PCM fs96kHz SOURCE: There are settings here again for Direct and Stereo; I think I have it set on Stereo. What should this be on? DIGITAL FORMAT SOURCE: The settings here are for Surround or something else; I have it set for SURROUND....is this correct? Thank you in advance for any assistance with this.
