I plan to have that BD reviewed for Friday at dvdfile. what an INCREDIBLE disc and INCREDIBLE sound... especially that two-channel PCM track (getting the Marantz 8002 for full-TrueHD decoding in 5.1 this week).

1080p and lossless audio. EVERY BD should have them both.

One question, I would like to compare UK release of Surf'sUp with eastern europe release....

from paidgeek I have info that UK release is 24bit DolbyTrueHD, I checked eastern europe release on PS3 and that version had DolbyTrueHD track with around 3.2 Mbps.

So I would like to know if this 3.2 Mbps if it can be 16bit or 24bit track ?

if it's 24bit dolbyTrueHD I will take eastern europe version (czech dubbing is included, which is plus for me), if it's 16bit I will take UK version...

thanx in advance,
Marek

hello again,

I would like to ask about Blade Runner DolbyTrueHD track..., on highdefdigest.com in review is 48kHz/ 16bit

http://bluray.highdefdigest.com/1039...unner_cce.html

I just received movie, and I saw several times over 4 Mbps, I saw just first 10-15 miuntes. is there any info on net if they did 16bit or 24bit DolbyTrueHD ?

thank you,
Marek

Hi, I just jumped on the blu-ray bandwagon. I think this thread answers my question, but if someone could point me in the right direction re an explanation of PCM vs. DD 5.1 or DTS Master, I'd appreciate it.

Here's the question - Casino Royale, is it better to use the PCM audio option or the 5.1 audio option? I have the Denon 3808 receiver and the panasonic dmp-bd30 so I technically can get DTS Master Loseless (if the disc has it). My receiver should be able to handle pretty much whatever. The problem is when I put the audio setting as PCM, my receiver just says "multi-channel in." What does this mean??!! Is it DD or DTS loseless?

Sorry for novice question!

Think of DTS and DD as file compression (like Zip in windows or MP3 versus a CD WAV file) and PCM as the original file being compressed. PCM will be the preferred sound choice if the disc has both PCM and 5.1 (typically they mean DD 5.1 when it's labelled that way).

Your receiver is showing the info correct, it's just getting multi-channel sound in. It is neither DD or DTS as it is not compressed.

DTS-Master Audio and Dolby True HD are newer audio compression codecs for PCM sound that are lossless - meaning when you decode a Dolby True HD file it will be equivalent to the original PCM file that was being compressed with it. PCM audio takes up a lot of room on the disc (especially if it's 24 bit, 96KHz 7.1 channel sound) and so Dolby True HD and DTS-MA were introduced to reduce the size of the audio data but not reduce the sound quality.

Benes,

Thanks so much for creating this thread, and for your efforts to document so much detail. As a new Blu-Ray user, I have been intimidated by the multitude of audio compression techniques, and this info is very helpful in sorting them out.

The information on file sizes and bitrates is very useful, and it is interesting to see that the Blu-Ray advantage in total disc capacity is actuall being used on quite a few DVDs.

Our own eyes and ears are still most important in our personal evaluation any DVD, of course, but it helps to see objective data to balance all of the subjective perceptions and hype that permeates most discussion of PQ and Audio quality on the DVDs.

I hope you, and perhaps some others who have the necessary equipment will be able to expand on the listings on a continuing basis.

I have to check it more, but it seems that Resident Evil (first movie) is 24bit DolbyTrueHD, I will check rest of the movie to make sure...

According to this Blu-ray disc statistics site:
http://www.blu-raystats.com/stats.php
and High-Def Digest's review on the movie:
http://bluray.highdefdigest.com/manonfire.html
Man On Fire on Blu-ray Disc is recorded on a BD 50GB disc...as to the actual space it uses, I can't find anything either...

But with a runtime of 146 minutes encoded with AVC MPEG-4 @ a 1080p resolution and a DTS-HD Master Audio 5.1 soundtrack, I'd imagine there wouldn't be too much unused space on that BD50 disc.

I have recently purchased a PS3 and am somewhat confused about what audio setting to use, bitstream or PCM, to have my Onkyo TX-SR875 decode the TrueHD or DTS-HD Master audio Bluray tracks via HDMI. Can you tell me which will give the better audio result? The receiver allows me to chose one of the following listening modes: Dolby PLII Movie, Neural THX 7.1 or a variety of THX modes including THX Ultra2 Cinema. Is there a preferred mode for these codecs? Thanks for your help.

Since the PS3 isn't capable of bitstreaming high-resolution audio (DTS-HD MA, D-THD, DD+), select "Linear PCM" in its Settings menu. That way DD+, TrueHD & "core" DTS MA will be decoded internally by the player. If you select Bitstream, your 875 will only be decoding the DD/DTS "core" (standard) tracks instead of the high-res tracks. As for Multi-channel PCM post-processing, those are purely a matter of personal choice. The PS3 only decodes DD/DTS/D-THD as 5.1, but if you wanted to extract the rear channel from a DTS-ES Discrete track, for instance, you could apply PLIIx, Ultra2 Cinema etc on top of that to simulate the discrete nature of the original (provided, of course, you have a 6.1 or 7.1 speaker setup). Experiment with them and use whichever one sounds preferable to you... Or, you can bypass them altogether and just playback straight "Multi-ch PCM". The Onkyo 875 and PS3 threads go into more detail, so check those out.

Epson HC 3500 | Elite Screens Saker 100" MW | Vizio M70-D3 | Emotiva USP-1, ERC-3, XPS-1, MC-700, XPA-5, XPA-3 | Pro-Ject DC Esprit SB | Oppo BDP-203 | PS3 Slim | Toshiba HD-A35 | B&W CDM 1NT x 4, CDM CNT | Polk DSW Pro 660w x 2 (L/R Stereo Subs)| Monolith 12” THX Ultra (LFE)

Don't forget about wiring sound to your receiver. If you are using the optical or coax connection you are limited to 5.1 (DD or DTS). This is the same sound as you'll find on any standard dvd.

To get uncompressed PCM (or DTS Master Lossless) you'll need 6 analog cables (or have a receiver capable of using HDMI for both video and audio).

just an FYI.

F.w.i.w. 3 Lionsgate movies (Crank, Dirty Dancing and The Descent) contain LPCM 6.1, not 7.1.

Well, yes and no. Actually the LPCM stream contains 7.1 channels, but the back surround channels are identical. So it's not really 6.1 but also not really 7.1.

I have a Question (I thought this was the best place to ask this).
Is there a list for all Profile 1.1 titles out? I Searched but probably didn't look hard enough if it exists.

Having just watched this I think I know why you asked this question.

This is a fabulous looking title. Reference quality, and it appears that Fox was really taking advantage of Blu-rays bandwidth on this title.
