PCM DD+ DD True HD & DTS HD

I am sorry if this has already been posted. I have only seen something similar, but it did not answer my questions, so I will try here.

Pirates of Caribbean on BLue ray doesn't do the DD+ or DD True HD or DTS HD, it only has PCM. When I configure my player to be able to provide DD True HD for example, for other movies, it only allows Pirates to play in regular DD. But when I configure it to PCM, it displays "nulti channel" on my reciever. Is that what I am looking for it to do? What does that mean?

THanks in advance

Re: PCM DD+ DD True HD & DTS HD

is your receiver capable of true hd/dts hd? what kind is it, what kind of dvd player do you have, how do you have it set up? Do you have separate cables for each channel, or do you use an optical cable? - or - do you rely on an hdmi cable? need some more info....... good luck!

Re: PCM DD+ DD True HD & DTS HD

one more note... true hd sound will only be produced with a 7 channel surround sound set up I believe, or at least 7 channels being used (5 channels with bi-amped fronts)

Re: PCM DD+ DD True HD & DTS HD

I am using HDMI 1.3 and I have a samsung 5000 HD DVD/Bluray combo (with the updated drivers) and the Onkyo TX-SR605 with all 7.1 hooked up.

The movies with True HD and DTS HD Master all work perfectly. It is AMAZING, I just don't get the PCM stuff like on Pirates. I don't know what it's supposed to display/do or what it even means in comparison to the other formats I mentioned.

Thanks for your help

Re: PCM DD+ DD True HD & DTS HD

ok I think I have it figured out... this website wont allow me to post links, so google "pirates of the caribbean" and find the ping for the actual blu-ray website. its somethings like w w w. blu-ray. com/ movies/ movies. php? id=59 <===== minus all the spaces!

I read that the audio is 5.1 dolby digital. Meaning, the hardware (onkyo) can only put out as good of a signal as its software (pirates) allows. In this case, you are going to want to set the receiver to the DD Master HD (it will therefore default to the next best thing that the DVD can offer, in this case DD 5.1) Check out on that blu-ray website some other movies that sound great in 7.1 and see if the specs on them in fact say 7.1. If they only say 5.1 like pirates, then I am stumped and you might just have to accept the DD 5.1. Let me know the results...

By the way, what speakers are you running? I have the same onkyo receiver and love it. I actually just bought a set of KEF Q-series which I havent hooked up yet but cant wait!

Re: PCM DD+ DD True HD & DTS HD

Thanks, so when it says PCM 5.1 like a lot of Disney films do, it is basically just a touch better than regular DVD 5.1, or am I missing the point of what it is supposed to be?

I love my receiver! I haven't up graded my speakers yet, but I am running some old ESS fronts, a Polk center, and some panasonic rears. Not ideal, but I'm getting there

Wow!! So much wrong about this thread.

True HD is quite capable of being heard on a 5.1 system. As a matter of fact, the vast majority of True HD soundtracks are only 5.1. There are very few 7.1 out there.

PCM is not "touch better than regular DVD 5.1", PCM is equal to what you would get from True HD or any other lossless codec, because the PCM track is what they use to produce the True HD. Undecoded True HD = PCM.

The best audio you can get from Blu-ray is PCM. You get PCM from a PCM track, or by decoding TrueHD/DTS-HD-MA. The number of channels depends on the film, not the codec, and both 5.1 and 7.1 will play on a 5.1 system

Re: PCM DD+ DD True HD & DTS HD

Thanks Jeff,
But now I am still confused as to my first post. With PCM, my reciever (with my player set to the same settings that allow for a Dolby True HD signal) displays only two options; multi channel or source. Is this what is should be?

Help me understand PCm a little better. I understand it is lossless sound, 5.1, etc, but what SHOULD be displayed on my receiver and why when playing PCM 5.1 movies?

Thanks a ton!

Re: PCM DD+ DD True HD & DTS HD

Bryan, are you using HDMI? Does your player bitstream the new codecs to the receiver? If the Blu-ray player internally decodes the PCM and True HD tracks, then, yes you should read "multi channel" on the receivers display.

I'm using HDMI, and I think the player bitsreams the new codecs, but I am not sure exactly what that means.

The DVD player has three options to set audio:

PCM
Bitstream (re-encode)
Bitsream (audiophile)

I have it on "Bitstream audiophile"

Should it be different considering the Onkyo I have?

Re: PCM DD+ DD True HD & DTS HD

Set it to "audiophile" and bitstream it to the receiver and let the receiver decode it.

Cool, that's where I have it. and according to what you said before, the correct display is "multichannel" on the receiver, correct?

Re: PCM DD+ DD True HD & DTS HD

Yes. Here's something to try for peace of mind. Play a blu-ray with PCM 5.1 or 7.1. Then using the onkyo remote hit the display button. First it'll say multi channel and every time you hit display it will go through info in the current audio format playing. One will say PCM 5.1 or 7.1 depending on the source. Then, you'll have proof you're playing the PCM track and not just regular DD 5.1. Try it. When you play True HD and DTS HD Master you see that on the display. With PCM it just comes up multi channel, but, rest assured you're getting what you want in that mode in that mode.

As was explained, your Onkyo will say "Multichannel" when playing multichannel PCM.
