Are you saying MLP is not included in this and must be paid for additionally?
DVD-A allows for 24/96 in surround and 24/192 in stereo. Take for example Alicia Keys - Songs in A Minor. It's a 5.1 DVD-A @ 24/96. I have more DVD-A's with a high resolution, but I don't know by heart which ones those are and I'm not at home right now.

Also, I think TrueHD is 'just' an extension of MLP.

To clarify:
DVD-Video allows LPCM stereo audio up to 24/192, (with limited video bit rates of course).
DVD-Audio is required for ANY flavor of 5.1 LPCM, MLP compression is required.

The line between DVD-V and DVD-A is blurred by many releases called "DVD-A" and "HDAD" which actually use DVD-V structures and 2-ch LPCM audio. Likewise there also pure DVD-A releases with 2-ch LPCM, early JVC releases in Japan are an example (these have no menus or images, just audio).

For user-created discs, anything is possible if your software will allow it, but no DVD-A or DVD-V can exceed roughly a 11Mb/sec rate.

If all that's not confusing enough, you can also put high-res 5.1 audio files on a DVD-ROM as long as your player supports it, the player just needs to spin the disc faster to obtain the required bit rate and buffering.

Toto, Falling In Between is an excellent concert Blu Ray.

I was referring to what is allowed (the maximum) without compression. To get multi channel 24/96 you MUST use MLP compression but the highest multi channel you can get is 24/48 (or 16/96) with LPCM (non compressed). TrueHD is built upon MLP. MLP is a fixed data rate and TrueHD is more advanced and variable date rate with added meta data.

Why would you care if it's compressed or not compressed?

I don't and if you read my previous posts (which you quoited) you will clearly see I was responding to rdgrimes post and even ask the same of him.eek.gif

No surprise with Steve Wilson involved.


I've noticed that a few of you have recommended Anesthetize on BD. It is a great concert, don't get me wrong, but if you like Porcupine tree, "Arriving Somewhere" on DVD sounds a whole lot better IMO. At least on my system anyways. And it gets better the more you turn it up!

I almost forgot too add.
Adele: live at the royal albert hall.(BD)
Diana Krall: live in Rio. (BD)
Alison Krauss: a hundred miles or more. Live from the tracking room. (DVD)
And the list goes on...

The sound on the "Always Somewhere" DVD is very good, but the title of the thread is "Bluray multichannel audio", so....

I prefer the audio on Anesthetize to AS, but they're both very good and wouldn't argue with anyone who preferred AS.

Hey Bfreedma, I absolutely respect your opinion! To each their own I guess. I just watched both concerts back to back, but I still think Arriving somewhere sounds better... On Anesthetize, a lot of the vocals seemed a bit washed out because of the synthesizer blasting in my right ear. And the drums didn't have that "slam" like on AS. Also, I couldn't make out half of the bass guitar, and a lot of the acoustic guitar wasn't there. I'm just being too critical I guess??? Its still a great concert. Enjoy the music!

I have both, and Anesthetize is significantly better SQ, so if your system doesn't show that, I'd suspect a setup issue.

One thing to point out is Steve is not afraid of putting a big load on the center channel, so if yours is either not capable enough or placed correctly, then soundstage balance will be off.

I actually custom built my center to enable me to get the absolute max out of S. Wilsons masterpieces:

I have to agree. The SQ for Anesthetize is among the best in my collection, although Arriving Somewhere isn't bad either for a DVD-V.

if you want to test your equipment recommend a demo blu ray disc on blu-audio.pl recorded in 192kHz/24 bit in all formats 7.1,5.1 stereo binaural & 8.0

Chris Botti "Live in Boston" and "Live with Orchestra and Special Friends"
Diana Krall "Live in Rio"

I'm going to disagree on Diana Krall. I have two copies of that disc. (Don't ask.) I don't think it's even close to being in the same league sonically as the Chris Botti disc.

I'm a huge Diana Krall fan. However, I think the Diana Krall disc is tier 1 or tier 2 audio as compared to the reference level that the Chris Botti disc is.

The Botti disc even looks better. I enjoy both discs, but the Diana Krall disc isn't, IMHO, a reference disc.

what about Black and white nights? (Roy Orbison) BD done in 96/24. great sound! From the first song,( that blew me away!)
looking forward to more stuff being put out on BD, as the studios have turned on the other 2 HR formats.
