Tigre -- what a phenominal announcement this is !!! I would not have thought it technically possible and I'm still having a few reservations about it (is it _really_ possible?) But the folks at Hi-Res say this,
The audio specification for DVD-Video discs includes 96kHz/24 bits for stereo programs as well as Dolby Digital or DTS for 5.1 programming (or 2.0 for that matter).
Hmmmm...... this has rather large implications! Sure would make backing up discs a lot simpler and ultra-less expensive than buying dedicated DVD-A authoring software.
I'd really, really, really like to hear Wilke's take on this one !! :-)

Definitely. You might have missed this, but I have got the Chesky DVD-Video "Chuck Mangione - The Feeling's Back" from a public library and created some test samples from it for 24/96 vs. 16/44.1 listening test. The samples are here:
http://www.hydrogenaudio.org/index.php?showtopic=13054& You can have a look yourself using a wave editor: They are true 24/96, nothing upsampled or similar.

AFAIK there is no free software that is able to create DVD-Video containing 24/96 LPCM audio. There has been a thread at doom9 some months ago, a developer said it wouldn't be much of an effort to code, but it hasn't happened yet.
Extracting audio from 24/96 DVD-V is quite easy though and 1:1 copies (backup) should be, too.
Yep - stereo audio at 24/96 is indeed possible, and done, on DVD-Video.
Your biggest problem is that most won't do it as it leaves so little bandwidth for the video component, which is compulsory in this format, even if it's only VideoBlack it must be there.
You can also do uncompressed surround in DVDV too.
Again, biggest issue is the bandwidth it all takes up as you are limited to 6.144 MBPS in DVDV for Audio, whereas it's up to 9.6 MBPS in DVDA. Not to mention that DVDA is starting to appear in Car systems, but DVDV never will.
It's horses for courses, and I'm in favour of anything that promotes hires PCM over the abomination that is DSD.
And another point .... when you really think about it, an automobile is probably one of the least appropriate places on earth for an audio listening environment (atrocious acoustics, engine/road noise), yet I can understand (I guess) the desireability of maximum 'compatibility' with existing formats.
Still...... will you or I ever (in this life or the next) appreciate 96/24 in the back seat of a station wagon going down Interstate #67? And frankly, would you wanna cart your expensive hi-res dvdas around in the car?
Makes you wonder why so many producers _always_ take their mixes out to the car? And there's me thinking that the RIAA have got it right and blaming downloads!
If only the trend towards overcompressing the masters would stop, CD wouldn't be so exhausting to listen to!
Go check out an old one from 10 years ago. Neil Young's Harvest is a good example. Rip it, and look at the waveform. Now do the same with a modern one, and see how many of the samples are actually "over" 0dBFS.
