Seems that EX print will be never be advertised. I think that the best think is to go on www.dolby.com or www.dtsonline.com (remember that when one movie is DD-EX encoded it will be also the DTS-ES version).
In Italy I never found any sticker or something telling us if it is EX or not. I've projected Star Wars and my copy didn't have any advise.
The problem is that the only theater that, at that time, has EX, asked for a change because "our copy is not EX recorded".

Wait... Do you have DTS ES decoder? I heard that DTS ES connected to DTS player will activate itself automatically IF the movie is ES encoded...

Karen, I believe that to do that there is a "bit" in the digital data that tell to DTS-ES that is time to turn on, right?
So, at the moment of encoding you know that the soundtrack is in ES. So why don't you put something on the disk itself? It will help who has SA-10 with DTS. And you will demonstrate more "attention" than Dolby...
It could be helpful to find "es" beside the title of the movie. Like:
"Star Wars - ES"

Does the new multiplex has CP650 or CP500? I know that CP650 will switch in EX (if installed) automatically. CP500 has to be manually (or via automation) selected.

EX/ES works in a very simple mode: a Dolby Stereo matrix code is applied to Surround Left and Surround Right during recording to put a Back Surround channel. Then a normal Dolby Stereo decoder will elaborate the LS/RS signal to "re-create" the back surround channel. The SA10 from dolby (the dolby unit for EX decoding) is just a modified CP45. The main difference is that a regular Dolby Stereo soundtrack will have 4 channel from a source of 2 channels; an EX decoder will decode 3 channel from 2. (like the center channel!).

If you play a NON EX soundtrack with the EX decoder activated, there will be a Dolby decoding in a non dolby encoded soundtrack. Like playing a Mono print with a Dolby SR decoder: it will be different than the director has intended it!

DTS-ES will change from "normal" to "ES" automatically instead.

Tell to your friend at multiplex that (if they have CP500):
1. Upgrade the Cp500 to last version, "1.61 EX". With that software version, if I remember correctly, a Dolby Digital on SK8 will automatically turn on the SA-10. So they'll have to set their automation to pulse the Cp500 to SK8 at film start.

Hope that this can help you. I believe that we understand better each other if I write in Italian and you write in Spanish...

I know that to have ES automatically switch, you should hav a DTS player plus a DTS-ES decoder. You'll have back surround also with DTS+SA-10 but not automatically.

Doesn't CP650 will automatically recognize Dolby EX???

Another reason to buy DTS decoder...

Karen,

Fantastic!!! I didn't know.

Did you say that ALL screens in that complex had EX? Are you sure?

John, when I heard that for 1st time I didn´t belived. 24 screens all with THX and DD EX???, no way.
But the people there is very nice and I asked for a visit of the booth and I had to eat my words. The 24 screen are equipped with Dolby CP650 with EX adaptor (I don´t remember the model. DA10?? and a new THX net crossover (is that the name?)that I suppouse is the next model from the old fashioned black box that I have in my THX screen.
Cinemeccanica Victoria 5 and CNR 3-35 platters and Decatron built-in set rectifier, lamphouse and automation system.
The megaplex is called Kinepolis Paterna (www.kinepolis.com) and I have to recognize that if I had to pay to watch movies it will be my first choice but...they are the enemy.
Saludos

It is strange that at Kinepolis there are CP650+ SA-10 (the surround ex adapter from dolby) since CP650 has an add-on card to have EX.

DTS ES is better not only because it switches automatically in ES.
I heard that DTS-ES adaptor has two different equalization: one for "normal mode" and one for "ES mode". So maximum quality is offered for each show.

Dolby one is just an old CP45 refusbished. And has ony one equalization.

DTS is cheaper and, like dolby one, works with Dolby Digital and SDDS.

So, why I never saw any DTS-ES????

Isn't what I said?

Nothing special? I know a theater manager that buoght SA-10 for Star Wars and not DTS-ES because "there are more DD-ex title than DTS-ES ones".
Once I told him that he can have back surround with their SA-10 also with DTS sound and he told me "no, if I use sa-10 with DTS I'll never have the back surround".

Karen, I believe that DTS should advertise better their products...

they have NO EX. Not a single one in how many screens?
