Tech specs include DTS-HD Master Lossless Audio and standard DTS 5.1 surround options. (Note also that 'Uncommon Bach' is compatible only with HD DVD players with HDMI or optical outputs.)
Of course all HD DVD players have HDMI and optical outputs so I guess all are doubly compatible in case one output breaks.
Except the XBox 360 with HD-Drive which doesn't have HDMI.
It shows this release will be DTS-HD MA. I don't think any HD DVD players exist to decode that and I don't think any decoders exist that can be connected by HDMI 1.3 to decode it. It isn't a very exciting release if that is correct and the best quality can't even be decoded currently. Guess it is a release for future enjoyment.
Hi!
You're absolutely right! If you ask me this release is completely pointless!
If they don't put any video content along with lossless surround sound on it, there is not a single advantage over a DVD-Audio.
And as you correctly observed: there is currently no player with a built-in dts-HD decoder (they only decode the core stream which is nothing more than the regular bare-bone dts with max. 1.5Mbps) and currently there are no players that can output the original bitstream. We can hope for an update for the XE1 (that's the flagship player in Europe) and probably it's American counterpart, because it has a HDMI1.3 output and supposedly the right chipset which could output the bitstream.
I was really hoping for some exciting music releases in HD, but this is certainly not it!

"If they don't put any video content along with lossless surround sound on it, there is not a single advantage over a DVD-Audio."
Is that entirely accurate? The Chris Botti Blu-ray has audio encoded at 13.8 Mbps. Isn't the maximum data transfer rate of DVD-A 10.08 Mbps (assuming no video of any kind)? DTS claims the maximum transwer rate for HD-MA on HD-DVD is 18Mbps. But this is where I get muddy - if audio is 96/24, does a higher bitrate really mean better quality sound?

The new Onkyo receivers can decode HD-MA but there are still no players that output it.

DVD-A can only do 96kHz/24-bit 5.1 while Blu-ray/HD DVD can have 192kHz/24-bit lossless 5.1 and at least 96kHz/24-bit lossless 7.1.
Hi Chris,
as far as I could find out, TrueHD allows for a maximum of 96/24 for multichannel application and the 192/24 only for stereo (same as MLP on DVD-Audio). And if I read the DTS web site right dts-HD Master Audio does not offer an 192/24 option at all (not that it would really make a difference if you ask me).
I don't know about the possibilities of the uncompressed PCM on HD DVD and Blu-ray concerning the sampling rates.
You're right of course about the two additional channels, but AFAIK there are unfortunately no releases so far that make use of it (at least in the case of the computer animated penguin musical Happy Feet I think this was somewhat a missed opportunity to provide a TrueHD track with only 5.1 even though DD+ track is DD+5.1EX (also not DD+6.1 or 7.1 )
Best regards,

I can't determine for sure that Dolby TrueHD can go beyond 96kHz for 5.1 either, but I believe it can. Here is one of many articles I have read that indicate both DTS-HD MA and PCM can be at 192kHz/24-Bit at 5.1. Will the difference between 96kHz and 192kHz be audible? I don't know the answer to that one, for me I think the answer is no, but I am 55 years old.

Hi Chris,
Reliable information on this seems to be a bit fishy and I don't know how far I can trust any such claims when they are not coming from Dolby or DTS themselves. I just tried to find something on both their web sites, and they both talk only about 96/24 on their overview pages here and here.
I even couldn't find something in the whitepapers that Dolby publish on their web sites.
But I agree that this discussion is probably of an academic nature, especially if you take into account that all the HD DVDs I know of with TrueHD seem to use only 48/16 anyway
(Unfortunately, my Toshiba XE1 player does not display these details and I have to rely on third party information like the reviews on http://www.highdefdigest.com/.
Best regards,
Oliver
I have it but I have only a BlueRay Disc player, so I have not been able to play it. Still, considering its lack of any new audio format makes it less interesting to me. OTOH, some Sony BRDs have MCH uncompressed PCM tracks................I wonder if Kal has checked this disc out yet???
Quite a few HD DVDs have lossless TrueHD tracks. The strange thing is that most of the music releases don't.I have it but I have only a BlueRay Disc player, so I have not been able to play it.
