It's still PS3.

The codec allows the PS3's decoder to downmix 7.1 tracks to 5.1. But PS3 should only do this when it detects a receiver that can only do 5.1.

So PS3 fails to detect the receiver's 7.1 capability and wrongly downmixes it to 5.1. That's why PS3 is saying 7.1 while your receiver says 5.1. The New Line's main movie uses this channel remapping technique.

But the New Line HD logo at the beginning of the disc don't, that's why you're getting 7.1 on your receiver. Meaning even if your receiver is 5.1, PS3 will not downmix the audio. It's up to the receiver to downmix, but to the receiver's own standard, not to the intended map by the decoder.

1. I did not say never (think real hard about how the PS3 works). I said - I can not comment.
2. Only a handful of 7.1 titles decode and output as 5.1 lossless DTS-HD MA on the PS3.
3. All other 7.1 titles have no issues decoding 7.1 lossless DTS-HD MA on the PS3.

hugh/saprano - your posts are great examples of why I seldom participate on forums.

I was just trying to help ;-)

i think he just gave an hint about an update........i hope.

You think?

[saprano]

why didnt sony say something about this before the update? they just made it worse.

[halmo20]

So what is he saying?

The 'Limited' logo means that PS3 will decode 7.1 and put it out as 5.1 when the type of encoding that New Line is using was used?

That means Sony knew about it and it was the limitation within the decoding software used and was implied by the 'Limited' logo...

That in turn implies it's not a bug????

This thing is getting really confusing really fast..

Exactly how did they make it worse?

DTS HDMA has SEVEN different 7.1 configurations that can be used in both the mixing stage and decoding stage. But the number of 7.1 releases as compared to Fox's DTS HDMA releases is not that big. It's a minor annoyance (still annoyance) but at least you get to listen to lossless in 5.1.

Users with BD players that have DTS HDMA bitstreaming have had similar problems, mostly due to how the receivers are decoding this stream. The point is not that I don't want the PS3 to solve all of these minor problems; it's that even now, we're at the early adopter stage where SCE and receiver manufacturers are experiencing growing pains.

So enjoy your discs and keep an eye out for new PS3 firmware announcements. Enjoy the moment! Live it!

I understand what your saying, but what i ment buy made it worse is nobody would be getting upset and going crazy( maby a little but not like it is now) if they let it be known before the update.

The "Limited" logo only means that we can't manually configure the channel remapping ourself. The PS3 decoder will do it for you, but that's where the problem is, the PS3's DTS channel remapping is buggy.

So it is a bug. Expect a fix soon.

[saprano]

or you can do this

Would you people with 7.1 setups and those "special" NL titles try to uncheck all audio outputs except 7.1 in your PS3 audio settings and try the movie out and report back your results including your receiver? Maybe the PS3 will be forced to properly decode 7.1 then.

[saprano]

it works to.

I knew about that, and yes it works. But you don't have to uncheck all, just the 5.1 PCM frequencies only.

But then you have to set it back to automatic to enjoy all other 5.1 titles!

[saprano]

yea you got to go back and forth depending on the movie, it sucks but theres no other choice until the update.

Question to you (no sarky): does your receiver manual tell you about the 7 ways in which a DTS HDMA bitstream can be decoded by it?

Sometimes giving too much flexibility and choice is not a good thing. People get confused. I hope they'll fix this issue soon before New Line issues LOTR in 7.1 DTS HDMA. Playing that at reference level will make you shit in your pants and bring tears in your ears but not at the same time.

No i dont think my receiver does that, and speaking of LOTR, yea the LFE in those movies is nothing short of amazing. and this is only dolby digital.

[Ectoplasm]

I think it's funny how picky people are being about all of this.

It'll get worked out!

Really, in this day and age, we should all be amazed that we can get this out of a machine costing as little as $350 in some countries.

Sometimes I feel like former HD-DVD zealots cling to any anti-PS3 argument just to save face in the wake of losing the war.

I read about people on HDD and AVS doing this, and it was just sending out silence to the 6th and 7th speakers, so it doesn't work with some. I suspect people who thinks it does work either forgot to put their ear to the speaker or the speaker was still matrixing.

Don't worry, an fix from Sony will come. They may not have known about this problem since it's limited to a few discs.

[aiman04]

Nobody is worried, and nobody's complaining. I'm confident that we'll get a fix soon.

We're only discussing the issue here. I'm sure everybody learned something from this discussion.

[saprano]

yes we did.
