I just bought a Panasonic DVD player(DVDF85) with DVD-A capability. I have it hooked up to my receiver(SONY) via the optical connection. When I play a DVD-A disc the receiver sees the signal and decodes it as as Dolby Pro Logic- not 5.1 multichannel. Is this right? As far as I know everything is set up right in the DVD menu and it does play DD & DTS DVDs ok. Must I use the 5.1 analog outputs instead of the optical to get multichannel to my receiver?
