    As in Pulse Code Modulation vs. DSD in the context of Codec methods?
    I am sorry, I have no opinion on the matter. I am sure you do. So, don't mind me, I just want to talk audio and pie.

    I'am sure I don't know what your talking about :o, I seen the setting on many of the DVD players that I have owned and wondered when PCM should be used instead of bitstream.

    ah, I see. Here is what recommended:

    Bitstream/PCM: Set audio output to bitstream. The only reason you wouldn’t want to use bitstream is if you’re not using the DVD player’s digital audio outputs. Almost all DVD players have PCM set as default, PCM will not send Dolby Digital or DTS to the receiver even if the DVD player is compatible with those audio formats. Countless new DVD player owners will listen to stereo PCM transmitted to their receiver over digital outputs, wondering why the receiver isn’t detecting Dolby Digital or DTS.

    Translation: if you are using coax/optical, then choose bitstream, if you are using RCA, then PCM.
    I am sorry, I have no opinion on the matter. I am sure you do. So, don't mind me, I just want to talk audio and pie.

    that I am pretty sure don't really matter, since 5.1 is in pure analog space, so the option is irrelevant. Assuming you are talking about SACD/DVD-A multi-channel playback.

    when I watch an HD DVD I use the 5.1 analog output so that I can get DD+ to my receiver with out the receiver converting it to DTS (so I think) and wondered if that PCM would be a better choice in stead of bitstream in this situation

    Another example of when you should use PCM is if you're using a DVD player as a transport with an external DAC in a 2 ch system.
    5.1 and 2.0 ch Basement Media Room: Outlaw 975/Emotiva DC-1/Rotel RB-1582 MKII/Rotel RB-1552/Audiosource Amp 3/Polk LS90, CS400i, FX500i/Outlaw X-12, LFM-1/JVD DLA-HD250/Da-Lite 100" HCCV/Sony ES BDP/Sonos Connect. DC-1/RB-1582 MKII/Sonos Connect also feed Polk 7C in garage or Dayton IO655 on patio.
    2.1 ch Basement Gym: Denon AVR-2807/Klipsch Forte I or NHT SB2/JBL SUB 550P x 2/Chromecast Audio.
    2.0 ch Living Room: Rotel RX-1052/Emotiva DC-1/Klipsch RF-7 III/Sony ES BDP/LG 65" LED.
    2.0 ch Semi-portable: Klipsch Powergate/NHT SB3/Chromecast Audio.
    Kitchen: Sonos Play5.
