mm- I do not doubt you own a receiver that decodes DTS, but I do doubt you have a receiver that can decode DTS-ES. Let me explain. Even though someone might have a DVD with the Dolby Digital Logo on it they must have a Dolby Digital compatible receiver. Agreed? If they had a Dolby Pro-Logic only receiver they would not be hearing Dolby Digital.

Just because you have a receiver that is DTS compatible does not mean you are hearing DTS-ES sound, even if your DVD bears the DTS-ES logo. Does your receiver bear the DTS-ES logo?

To hear DD you need:
1) DD media
2) DD decoder

To hear DTS you need:
1) DTS media
2) DTS decoder

To hear DTS-ES you need:
1) DTS-ES media (gladiator)
2) DTS-ES decoder (receiver that bears the DTS-ES logo, ie- Denon 3801)

Do you see the logo there? In the middle towards the right.

Sorry if this explanation seems drawn out but I just wanted to make everything clear. Please correct me if you feel I have stated something wrong.

Dolbytone- I pretty much agree with your philosophy on the matter, but I have yet to hear DTS-ES so I won\'t comment with any opinions on the format yet.

people, people, people. I heard of sdds before. now you just notice. ( I knew dolbytone and mm knew this before.)

i remember posting this before i will post it again. anyway, less compression means better sound quality right?

1 sound channel: mono
2 sound channel: stereo
3 sound channel: surround (dolby surround)
4 sound channel: dolby pro logic
5 sound channel: dolby digital
5.1 sound channel: dolby digital and dts
6.1 sound channel: dolby ex and dts-es
7.1: sony dynamic digital sound
8.1: mystery maybe lucasart thx?
9.1: mystery-thx?
10.1: thx
10.2: thx

i think the highest as of right now is lucas art 10.2 sound channels. oh, thanks for information about sdds bit rate...2.3 megabit per sec...that\'s alot. i remember playing the matrix using dolby digital running at 392 kilobits.. or about .39 megabits per sec...they probably compress it to use less memory...

OK...

1. You need a DTS-ES Receiver !!! NOT just a DTS Receiver !
2. You need the medium (Gladiator)
3. You need a Rear Center Speaker !

Thats it... 6.1 !!!!!!! (Sorry for those "!"

)
BTW: I don´t like it too, I think it only gives you an advantage, if you have a BIG Livingroom... A very BIG one, ya know !

To bring it to an end:
DTS is better then DD.
"Normal" DTS is NOT 6.1 ! It´s 5.1, just like DD... so you don´t need an extra Rear Center !

ONE LAST THING !
If you play the GLADIATOR with a "normal" DTS Receiver (NOT DTS-ES) it will play the Sound just like DTS (5.1) !!! The Centersignal then is delivered to the two Rear Speakers... I can prove it, because I´ve seen "Spleepy Hollow" on my equipment... "Sleepy Hollow" also supports DTS-ES ! But I only have a "normal" DD, DTS Receiver (5 Speakers) !

YOU DON´T NEED DTS-ES !!! JUST LISTEN TO THE MOVIE WITH DTS SWITCHED ON !!

Hear it, love it !

Dude, that is just all ****ed up. First of all SDDS is NOT 7.1 because the "subwoofer" channel isn\'t band limited, it\'s full range. 3 Channel isn\'t Dolby Surround, it\'s stereo sound with a center channel. 5 Channel is DD, but 5.1 is DD as well? WTF? Did you just make this **** up? Since when does THX allow you to have more channels? You\'re playing the exact same sound formats through a THX system that you do through a non THX system so where do the extras come from?

« **Reply #35 on:** January 01, 2001, 08:08:51 AM »

Come on, it isn\'t that hard.

Dolby Digital = 5.1 = 2 front speakers, 2 rear and 1 centre + 1 for sub.

DTS = 5.1 = 2 front speakers, 2 rear and 1 centre + 1 for sub.

The difference between DD and DTS is the bitrate. DTS uses a higher bitrate than DD = higher quality/resolution sound. BUT it takes up more space on the DVD, so some movies with DTS doesn\'t have much/any extra features. Or the picture bitrate might be less than a DD version to make room for the DTS sound.

DD-EX = 6.1 = 2 front speakers, 2 rear and 2 centre (front + rear) + 1 for sub.

DTS-ES = 6.1 = 2 front speakers, 2 rear and 2 centre (front + rear) + 1 for sub.

Again, the same differences apply between DD-EX and DTS-ES.

You can easily listen to DTS-ES without a DTS-ES decoder - IF the decoder can decode regular DTS. The only difference is that you abviously don\'t get the centre rear channel.

But bottomline is that DTS offers better sound - technically, though DD sounds just fine to most people.

EDIT:
Doh! I just saw the first page ... and not the second ... before I replied. Well, I\'ll just let it be anyway.

so, at any rate, if theres a difference between DTS and AC3, i cant hear it. me thinks its just a BS scheme to make me spend more money on some fancy name [ES], and just to say i have the top of the line equipment.

There is very little difference between DD and DTS. As long as you have a solid receiver who cares. I don\'t see how anyone an be confused ever again on 5.1, 6.1, ES, etc.. After all of these messages. If you are confused then just spend your money and enjoy because you won\'t understand.

As far as that whacky message listing the different levels throwing in a bunch of THXs. THX can be any level. You can have 2 channel THX I think... All it is is a quality standard. It\'s a gimmick to throw on an extra 15% to equipment. heck, probably more than that.

Finally, just watch the movie, if it sounds good, then enjoy. If it sounds like crap, then buy new stuff..

And if you have more questions, you really should go to hometheaterforum.com... it\'s much better for this talk..

mm... I´m depressed...

For the first time here, I think you don´t understand a thing of what we are talking here...

DTS-ES is just an add-on on the normal DTS !
For the normal DTS YOU DON´T NEED A CENTER REAR !!!
If a DVD supports DTS-ES, than you can enjoy it on you equipment just like DTS. If you want to have DTS-ES or DD-EX then buy a new receiver and a Rear Center... but if your receiver supports DTS, then I wouldn´t do it !
DTS is the same as Dolby Digital, only the Bitrate is higher - and YES, you wll hear the difference between DTS and DD, just switch from DTS to DD during the movie...
DTS sounds "richer"...

And please post it in here if you finaly get it...otherwise I´m getting nuts !!!

The next thing I´ll do is to send you my phonenumber, so you can call me for any questions... *lol*

Hey I have the same problem as ddaryl. I\'m trying to play Samurai-X. I know my receiver and pretty sure my PS2 is set up right b/c I just played Perfect Storm yesterday and it decoded to surround channels. However, Samurai-X is just doing 2 ch right now. When I play the DVD my receiver says it\'s DOLBY DIGITAL 2/0.

I\'ll check the DVD menu and see if it has a setting but my PS2 and receiver are configged correctly.

So I was wondering if all DOLBY DIGITAL DVDs are 5.1 surround?

« **Reply #43 on:** January 02, 2001, 07:25:45 AM »

does the disc specifically say dd 5.1? i have many early DVD\'s that are only surround stereo.

mm

« **Reply #44 on:** January 02, 2001, 07:38:15 AM »

The only thing the disc says is the DOLBY DIGITAL logo.

So is that true surround or just 2 channel stereo?
