    If i recall the spec mandates that there be a lpcm track or MLP can be used as an option instead, but it also allows for other formats (which is why we see DD and DTS tracks). Correct me if i'm wrong but doesn't it also allow if wanted a DSD track, so long as the LPCM or MLP track is on the same disc?

    Thanks in advance for your responses!

    David, DSD is the encoding scheme used for SACD. As such, the DVD-Audio spec. does not call for inclusion of a DSD track. At least, I have never heard that. Note that DSD is an uncompressed encoding scheme that is used with SACD instead of PCM.

    I had to explain to a salesguy at Tweeter that while dvd-audio does use a compressed PCM digital format--MLP--it is a sophisticated LOSSLESS compression system! It is nothing like the MP3 format. Dvd-audio can also use "normal" PCM (written as "linear" or LPCM): several dvd-audios feature a 96kHz/24bit stereo track playable on any dvd-video player with 96/24 DACs. AIX Records dvd-audios have this, along with a few Warner titles.
    I am very sure Sony/Philips would never allow their DSD format to be put on a dvd-audio disc, since dvd-audio is their competition.
    Over at Highfidelityreview.com they have written this: "Dvd-audio Myths Debunked":

    Dvdangle.com has a very thorough explanation of the dvd-audio format: http://www.dvdangle.com/dvd_audio/up...g_to_dvda.html

    It is true that the use of DSD is allowed as an "optional" format on DVD-Audio format discs. There is not prohibition from Sony/Philips...the real question would be why?
