For Discrete\Matrix\24-96 streams.

A future relase of InterVideo's WinDVD Platinum seems to be your best best, as the latest one, 7, only supports the latest DD standards but not the DTS ones.

I read in the Intervideo site that WinDVD 7 Platinum seems to play DTS HD (it says something about "new" in the features comparisson page), I just want it to know if it was what I hoped for. But no!!
Thanks, man!!

DTS HD is nothing else than the brand name for the set of extensions that go beyond the core DTS standard. In particular, Coherent Acoustics' lossless mode of operation, extension to more than 5.1 channels, sampling frequencies of more then 48kHz and extension of bitrate range to the low end as well as to the high end are covered.

The new PowerDVD 7 Deluxe has full support for DTS-ES (Matrix and Discrete), NEO:6 and 24/96.
Finally!!!!!!

....with the extra $$ add in pack. (for MLP, at least)

Yea, that sucks but still is is the only app supporting extended DTS. The free filters outthere still don´t .

The WinDVD 7 Platinum version I have plays DTS streams but I don't know about discrete or matrix. What are those? Sorry, just audio dumb! So far, it has played DTS-CD and DTS movies. I think it might limit DTS-CD to 2 channel just like DVD-A though.

There are like 5 types of consumer DTS streams:

DTS-WAV: up to 6ch DTS in WAV container (for DTS-CD), 44.1kHz 16bits.
DTS standard: 2ch 48kHz 16bits or 5.1ch 48kHz 16bits (the last one, used in commercial DVD-Video with DTS audio).
DTS-ES Matrix: 5.1ch 48kHz 16bits with Back Center channel matrix-encoded within the Ls and Rs channels, from wich a DTS-ES decoder can retrieve this Back Center and deliver it as a separate channel, creating a 6.1ch environment (the same as Dolby Digital Surround EX). ES as in extended surround (or some like that).
DTS-ES Discrete 6.1: 6.1ch 48kHz 16bits, the Back Center is not matrix encoded but actually exists as a separate channel. DTS-ES decoder still needed to pipe the BC channel to the BC speaker, otherwise the BC channel is send to the Ls and Rs speakers (as if it were matrix-encoded and played in a 5.1 speaker system).
DTS-HD or DTS 96/24: is the DTS High Definition, up to 6ch 96kHz 24bits.

DTS NEO:6: is not an audio stream type but an upmixing algorithm for delivering up to 6ch from a 2ch source (similar to Dolby Prologic II).

The WinDVD 7 Pro version can decode DTS and DTS-HD but not DTS-ES.

Are you sure that 16 bits is correct for the mentioned DTS formats? I thought that DTS as a lossy codec does not use a fixed bit depth. I also have a DVD-A disc with a DTS track on it. The packaging states that it is 24 bits, which in that case should be the bit depth of the source material.

Mmmm, wheter it is or not, I can´t be absolutely sure. You should ask someone at DTS, but as far as I know 16 bits is the bitdepth used in standard DTS tracks (at least, that´s what they state in their website).
Your DVD-A is probably a 96kHz/24bits audio track, most probably MLP compressed, with a Video_ts part with DTS audio (for compatibility issues; if your DVD player can´t play DVD-A, then at least u can listen to the tracks in DTS, maybe...).

I'm not sure but I also think that DTS is a floating point format.
In this case 8,16 or 24 bits are meaningless, and only marketing stuff.

Yes, you're right, see ETSI TS 102114. But I think in contrast to MPEG, 24 bit input is not truncated to 16 bits, i. e. resolution is preserved as long as the bit allocation permits to.

Yeah, probably is some marketing crap.
And I don´t even like DTS (U$S 1000 for an encoder?!).
I´m just waiting for Dolby Digital Plus .

Certainly not only marketing, depending on the processor used to
implement it (i.e. runs on some DSPs without FPU), there is no such
thing as a "floating point format". Input into the encoder is
PCM, and it is for sure not limited to 16 bits.
Even the standard DTS (5.1) supports more then 16 bit.
The bitstream on a DVD is in 16 Bit format, though

In case of MPEG, input or output does not have to be truncated to 16bits. (example: Lame accepts 24bits input)
So DTS is no more 24bits than AC-3 or MPEG audio.

Surcode DVD DTS does take 24bits inputs. Though some filters report as DTS 5.1 16bits like AC3filter and Intervideo´s (might be a bogus report?). Ffdshow doesn´t report bitdepth, neither does PowerDVD.

Some DVDA discs have this high resolution DTS format on them. For example, both Frank Zappa DVDA discs (Halloween and Quaudiophiliac) use the format. They also have a regular DTS stream on them. The DTS HD stream is definetaly on the disc, but is unrippable...
