Can anyone tell me approximately where in the movie this occurs?  |  IP: Logged Phil Hill I love my cootie bug Posts: 7595 From: Hollywood, CA USA Registered: Mar 2000 posted 12-07-2003 03:46 AM                  Mike, it's at the part where she asks "Who is this girl?" and the guy sez it's his daughter Rachel.

Most ears cannot determine the difference between the actual thing and a pirated copy anyway as long as it involved top-of-the-line analog equipment that almost everyone can afford to purchase or already have in their possession. For eons, people have been pirating analog sounds and they were (and are, for the most part), happy with the quality. So who should really give a crap? I don't. As far as I am concerned, there is nothing out there worth pirating in the first place. This includes movies, (which 90% are mostly garbage that is not worth the polyester stock it is printed on), sound tracks, CD's, or what have you. RIAA and MPAA are running scared. Everyone knows that. It is a monster created by the digital technology. And, there is nothing they can do to stop it because any good quality recording can be done by technology that is upwards to 60 years old, if not older. That being -- you guessed it -- analog means. What I just said is a fact of life. Accept it. I have run (and so have most of you) movies that we should pay the customer to watch! OK - flame me....see if I care.  |  IP: Logged Frank Angel Film God Posts: 5305 From: Brooklyn NY USA Registered: Dec 1999 posted 12-07-2003 05:48 AM                        Paul G. said: quote: As far as I am concerned, there is nothing out there worth pirating in the first place.

OK - flame me....see if I care. Why flame you Paul? You are totally on the money. And you know what? GOTHIKA is one of them. In fact, I ran it as a FREE sneak and the patrons hated it. Those beeps are a digital code that pirates have hacked into the digital datastream on the movie SET and inserted into the film's soundtrack. If you use the hacker's special software that they make available free on their website www,hackmeifyoucan.com, using metacap debyterizer technology, it will translate the code into text on your screen. I've run the beeps thru this software and it translates thusly: THIS PIECE OF DOG POO MOVIE WAS PIRATED BEFORE IT WAS MADE....JACK VALENTI SUCKS.  |  IP: Logged James Falloon Film Handler Posts: 72 From: Wigram, Christchurch, New Zealand Registered: Oct 2003 posted 12-07-2003 08:06 PM                     Could it be possible to modify the timecode on the film to contain the print number. The DTS machine then interprets these and plays a series of beeps or something depending on the print number. Could that be their new "security enhancement". Anyway, thats my theory  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 12-07-2003 08:15 PM                        Rather than burn a different CD for each theatre or make a new sound negative (!) for each print, it would be easiest just to have a "hardware ID" value built into each player which generates some sort of identifiable sound element (like the beeps) when commanded to do so by the encoded soundtrack. Presumably DTS knows where its units have been installed (for the most part) and could track down "hardware ID xxxx" to a specific theatre. One would expect that there would also be "special" players for screening rooms, premieres, etc. which wouldn't generate the annoying information. Still (if this DTS code even exists), it wouldn't be any more useful than CAP code, as it would just identify the player used (and, presumably, the theatre), and not the actual pirate. It would be helpful for tracking down "inside jobs," but not for the "audience member with 24P camera" type of pirate.  |  IP: Logged James Falloon Film Handler Posts: 72 From: Wigram, Christchurch, New Zealand Registered: Oct 2003 posted 12-07-2003 10:09 PM                     ok, points taken Scott, that would be much eaisier to do. just take the BIOS / cdrom drive serial number (if it has one) or something BTW here is a slightly enhanced pic, basically the same as on page 4, it is interesting to note, that the first two tones do not seam to have harmonics, but that could be a feature of the mp3 encoding. Brad do you have that as an uncompressed wav file? i'm just interested to see what that would look like.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 12-08-2003 05:12 AM                     Sorry, I returned the recorder to it's owner already and didn't think to save it in wav format. Scott, I don't know why anyone would bother going to the immense trouble to pull the audio off of a digital format anyway when 2 channel SR is effortless to grab. I would assume most pirated tapes are mono anyway (well, at least the stuff that the studios don't actually make that gets into circulation).  |  IP: Logged Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 12-11-2003 08:35 PM                    I'm not quite sure that an ordinary DTS unit with its limited CPU power could add sounds to the output. Data is being delivered from the CD's to the decompression hardware but it would seem to me that to add...ADD not substitute...but ADD beeps to the track would require decoding the audio in software...mixing in the desired beeps...then re-encoding and delivering the data so that the audio can then be output by the same hardware. What does our new DTS rep say about what those beeps are? If this is in fact audio copy protection do we have a snazzy name for it yet? How about Pee Code (to go with Crap Code)?  |  IP: Logged Carl Martin Phenomenal Film Handler Posts: 1424 From: Oakland, CA, USA Registered: Feb 2002 posted 12-12-2003 06:46 PM                        have you tried calling dts about the "problem" with your system? if they can't troubleshoot it, maybe they'll replace it. if they have to keep replacing units, maybe they'll fess up. it's a long shot. carl  |  IP: Logged Bobby Henderson "Ask me about Trajan." Posts: 10973 From: Lawton, OK, USA Registered: Apr 2001 posted 12-12-2003 09:37 PM                     For DTS to "serialize" hardware keys into the CDs it will take them knowing exactly where all active DTS-equipped theaters are and exactly how many units are in operation down to the serial number. I strongly doubt there are any fully accurate numbers on that. One alternative may be utilizing a dongle. I have to use those damned things on my computer at work (one for FlexiSign Pro and another for Neon Wizard). It should not be too awful hard to put a parallel port on the older machines and simply use a USB version on the XD-10 models. Still, I think the whole copy protection effort is a big waste of time. Much of the pirated movies on the Internet come from DVD screener discs, often before the movie is released to theaters. IMHO, this effort is just going to make it more difficult for legitimate DTS-equipped theaters to play their movies.  |  IP: Logged Thomas Procyk Phenomenal Film Handler Posts: 1842 From: Royal Palm Beach, FL, USA Registered: Feb 2002 posted 12-13-2003 02:13 PM                     Perhaps all of these "DTS Beeps" and visible CRAP code are exactly the "barely-noticable-by-the-average-consumer" subliminal messages that the industry is using to fuel its curiously-booming DVD sales? "You know, Gothika really sucked but somehow I feel I still need to own the DVD." =TMP=  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 12-28-2003 02:38 PM                     Getting back to the point of this topic... Anyone know what the first "uncopyable" dts disc title is supposed to be? I heard that it was to be LOTR3, so I tried to dupe them out of curiosity and had zero problems. This whole thing all stems back to Valenti and will end up putting DTS out of business. At that point we will have Dolby Digital, which is what I preached to everyone back in the mid-90's to put in anyway after evaluating the 3 options. Few listened and purchased with their pocketbooks or went with SDDS because they wanted "the best" (again, deciding with their pocketbooks). At least it will be nice to only have to deal with one sound format.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 12-28-2003 03:03 PM                     I doubt there will ever be a unplayable DTS system as it would be virtually impossible to implement a system that would be playable on all the versions of firmware out there To copy a disk maybe a different story but to playit I don't think that will happen  |  IP: Logged Greg Mueller Phenomenal Film Handler Posts: 1687 From: Port Gamble, WA Registered: Jun 99 posted 12-28-2003 03:21 PM                        Back in the days of DOS and software anti piracy attemps. I ran into a number of programs that were so well copy protected that they would not operate in my computer. This problem varied from computer to computer. Eventually the software manufacturers gave up or went to dongles. Now we have on line registration. Time will tell I guess, but does anyone think that the pirates that the industry fears will not beat the encryption techniques? Or will not simply take a copy off the analog outputs of the DTS/SRD/SDDS systems? It's all pretty silly if you ask me. What moron would not wait a couple of months to have a real official non pirate copy with excellent picture and sound.  |  IP: Logged
