I thought somebody over at OT mentioned there was a date after which the encryption method used on DTS discs changed? Therefore, the method used so far wouldn't work on later films?

Yeah, they switched from the unencrypted AUD files to the encrypted AUE file in somewhere about 2005. I think Jetrell Fo mentioned he has a way around that on the OT.

Well looks like all good things must come to an end, from the 35mm forum:

"As is the case with 35mm prints in general, DTS/Datasat has closed up shop on their disc program. The release of "Terminator: Genesys" is the last 35mm title produced. There will be special venue showings of Tarantino's "The Hateful Eight" this winter, but once that is complete, that will be the end."

So DCP movies from now on then?

Seems that way

Will be Christopher Nolan happy, like most of us? Don't think so...

I would like to chime in and say that I have talked to one theater person I know and he said that the Datasat audio is encrypted and it isn't the same as the cinema DTS .aue file system so getting the audio and decrypting it are two totally different and difficult beasts at the moment.

Great thread. Thanks guys.

'Dunkirk' is getting a 70mm and 35mm release, would this just be limited to the Dolby Digital mix then?
There is an ATMOS mix, but I gather no way to marry the two.

On a side note, has anyone ever figured out what sound system 70mm IMAX venues use? I've seen The Force Awakens and Rogue One at the IMAX dome in San Jose, (R1 had an extended Dunkirk trailer) but all the info graphics at the museum only cryptically refer to the soundtrack being on a CD.

Good to know, thanks for the info Jetrell. Did he say if they changed the file formatting too or just the encryption type?

The 35mm would almost have to be DD, my Interstellar 35mm showing was and there is not much in the way of other choices. Not sure about the 70mm since Datasat said Hateful Eight was the last shipped disc. Someone could of taken that over I guess or maybe Datasat does one offs.

Maybe we should ask on the projector forum.
