A few more points:

We will NEVER stop supporting customers with CD-ROM drives.

The type of hard drive that will be used on our new player has not been finalized. When I am permitted to give you guys more info, I will (I know it's hard to wait).

Copying discs? The offical DTS company line is = do not do that.

The DTS lawyers should be happy. Now DTS is not liable if an individual copies a set of discs. But if the studio says it is OK then I don't see a problem. In my opinion the studio owns the discs. And if you are short some discs and would otherwise have to play it in analog I'd say the studio wouldn't mind, either. In a perfect legal world you'd probably have to get permission from the studios each time you copy a set of discs, but that can't happen. Plus the discs are useless without a movie to go with it. Even if you have a timecode generator, all you can do is LISTEN to the movie and not watch it.

Yes, you can copy DTS discs on the Mac and sell them on EBay for one million dollars each. Oh wait, I doubt you could get ANYTHING for 'em on EBay, but people ARE pretty stupid when it comes to that site.

I have seen someone selling DTS Feature and Trailer discs on Ebay. The movie was pretty old, but I don't remember the title.

Has anyone come up with a software implementation of theatrical DTS decoding? Seems like with the speed of today's PC's this should be possible. And now with 5.1 soundcards there'd be a way to get it out of the box.

Of course I am only thinking in terms of private amusement but I guess it's not hard to extrapolate to the next step which would be to implement the entire box on an ordinary PC with no extra cards (feed the timecode into an audio input). DTS on every screen for $700 a pop.

Jump ahead a few years: Disk distribution strictly limited to owners of real boxes. Underground distribution via Morpheus. hehehe It will get interesting.

hi Karen

Note my comments, I fully agree with you. That test was flawed and made in panic, imho, by Dobly who saw a threat coming from the 1/2 rate DTS.
Too me, the Dolby codec and its principles applied to the dvd market pose 2 serious, often recurring, problems:
1. its inherent caracteristics (bit sharing, low data rate, causing 93% of losses from the master , at 15:1 compression ratio etc)
2. unfaithfull to the original master (overall level, dialogue normalisation, which indeed DOES affect the work of the D/A converters in the reproducing chain, and downmixing, which KILLS dynamics imho ).

This is an opinion more focusing on the dvd software but still, most of it can be seen in the cinema world too.
Dolby is a convenient compromise (on the film print or for taking a small space on dvd). I would say DTS is to sound what Panavision-70mm is to film

Karen, I hope you didn't read anything into my "DTS fudged the test" post. I was only repeating what I remembered Dolby saying at the time of the test (sour grapes on their part I'm sure). DTS clearly has the better cinema digital sound system.

For David Stambaugh,

Hey, don't worry about it! I knew you weren't trying imply anything. I am happy to see that you are happy with us (DTS)!

hi

I was a bit stunned when I read your comment on dolby-dts test as what you said was exactly the opposite of what REALLY occured. (except that the full rate dts was ultimately prefered during this "blind" test run by dolby ).

cheers

hi Karen

if you want to read another example of flawed opinions against dts, read this: CLICK HERE

it's shocking to see the denial of the evidence (superiority of DTS) one can find over the internet.

best

David Baum, I just went back and re-read my original comments about the shootout. Note that I was careful to say I was going from my memory. I didn't have a copy of the original writeups or anything like that. If I got it wrong, I stand corrected. It wasn't my intention to state false information as fact. I figured if I was wrong, someone on this forum more knowledgeable than me would call me on it, which is as it should be.

I hadn't had a chance to respond to John Hawkinson's negative criticism on my idea for a single DTS Server to sound an entire mulitplex.

Single point of failure? Hardly. First, at least give me some kind of credit. I'm am not talking about picking up some cheapo Hewlett Packard Pavillion PC and trying to make it into a server. I seem to recall mentioning stuff like Sun and UNIX, etc. Y'know, enterprise level server stuff. Not amateur crap.

If you put a good fault tolerant server in place with full RAID capability or better yet a rack mount server cluster you will have something far more reliable and even more simple in operation from an organizational standpoing than a multitude of DTS players strewn across an entire multiplex.

Just look at what you have to spend per screen to outfit DTS. You're at nearly $7,000 alone for a DTS-6D unit sans integrated cinema processor. I'm pretty sure that, for under $20,000, I could put together a parallel server cluster that would be powerful enough and reliable enough to do the same duty as 24 or even 36 DTS-6D units.

Kodak's Digital Cinema Operating System envisions a central server for "Digital Done Right".

"SUN Microsystems is providing the server storage and networking platform for the cinema operating system and digital projector. The operating system will support the loading, scheduling, and playback of features, trailers and other pre-show content on multiple digital screens."
