In Reply to: Is it a DVD-Audio? Elusive Disc says it's not posted by racerguy on March 13, 2007 at 22:16:52:
To me, a "standard DVD-V with 2ch 24/96 LPCM" is a stereo DVD-Audio disc, but I understand that different people have different definitions of what constitutes DVD-Audio. (I believe the Massey Hall disc itself has a DVD-Audio logo on it, if that means anything.) However, if you are asking if the disc contains a hi-rez multi-channel layer, my understanding is that the answer is no.

A DVD-V disc is not a DVD-A disc. A stereo DVD-A disc requires a DVD-A player. A stereo DVD-V disc can be played on any DVD-V player. There have been stereo only DVD-A discs from cos. like Hi-Res Music. I have one. According to this the last DVD-A disc was November: http://en.wikipedia.org/wiki/DVD-audio
My understanding is that the primary specifications for true DVD-Audio are not only 24 bit word length and 48/96/192Khz sampling rates but that all "true" DVD-Audio's use Meridian Lossless Packing (MLP)or PPCM versus the lossy compression scheme utilized on DVD-Video discs (with and audio stream)LPCM.
LPCM is uncompressed PCM. You can't have "loss" if you don't compress it.
I am wrong in what I said about LPCM being lossy. I stand corrected and unfortunately it is not the first time or the last time in my life I will be wrong.
