I'm looking for the optimal audio menu settings for dvd-audio playback on a Panny RP91 dvd player? SPEAKER SETTING: multi-channel or 2-channel? DIGITAL AUDIO OUTPUT: ON (remaster off), ON (remaster on) or OFF? PCM DOWN CONVERSION: NO or YES? DOLBY DIGITAL: PCM or BITSTREAM? DTS: PCM OR BITSTREAM? Any other setup advice from owners of this player would be appreciated?
