CAP Codes and digital watermarking are only a few of many tools the MPAA uses to catch and convict the criminals who prey upon the industry. The job you save may be your own.
BTW, the MPAA does have a generous reward program for anyone that provides information leading to the conviction of movie pirates:

Would I send out screener tapes of, say, Spike and Mike's Animation Fest? Sure! Would I send out screener tapes of Star Wars or Spiderman? Hell, no!
Besides, small-town theatre owners are not very likely to want to pirate this stuff, since it would do nothing but hurt their own business.

Any moron can make a near perfect video transfer from a DLP screen!
Yes folks let's think about this for a minute. With a regular 35mm film projector, there are 2 or 3 shutter blades. So in essence there are either 48 or 72 images per second. Video shoots at 30 images per second and 30 does not divide into 48 or 72 without a fraction, thus a very horrible flicker will result in the taped copy. With DLP, there is no shutter, just 24 images per second. What this means is that any bonehead can take any old crappy video camera, point it at the screen (preferably on a tripod of course) and walk away with potentially a much better copy than that person could generally achieve when trying to copy a DVD because of DVD's MacroVision copy protection! Now sure the audio would sound echoey if the built in microphone was used, but many monitors have headphone jacks on them, and for those that don't, it wouldn't be rocket science for some determined low life to patch into the sound system directly.
No I do NOT advocate piracy and I have personally caught several bootleggers red handed in my theaters and confiscated their tape and scared the pants off of them, but let's be honest here, digital cinema is an open invitation to piracy.
CAP code? No I don't think so, for I've never seen the marks on a DLP presentation and it's not that effective anyway. As it stands right now, there is nothing to prevent someone from copying a DLP presentation to video. I have come up with a few ideas on my own and passed them along, but I am not sure if they will implement them or not. I'll post a couple of them here for your reading enjoyment:
*Do the "ET" trick. When ET was released in 1982 I noticed that the ending scene where there is no dialogue, but random shots of everyone staring at the ship in awe as ET leaves Earth that the shot order varied between prints. Very sneaky and very effective! Such a thing should be easily able to be accomplished with DLP, for it would just be a matter of modifying the digital files between "prints".
*Do the Yoda thing. When Empire Strikes Back was released some of the audio was changed. The most obvious example is when Luke first meets Yoda. Luke says "Hmmm, I feel like" and then Yoda replies "feel like what?" Luke does a quick turn around and in half of the prints Yoda moved his stick in front of his face and in the other half of the prints Yoda does the same movement, but says "eeeeeeeehgh!" Little audio changes like this should also be changed easily enough.
*Change a number on a door. This is my favorite and to my knowledge has not been implemented. Let's say Jar Jar is running down a hallway trying to escape death from an attacker. (Let's hope the attacker wins!) As he stops in front of a door that door could have a number on it or the nearby wall. How hard would it be to make that number the "DLP print number"? Not too hard I wouldn't think.
*Even more subtle, but highly effective would be to take a shot that is long to begin with that the director wouldn't mind shortening, such as an establishing shot, and chop frames out of it to signify the print number. Let's say there is an establishing wide shot of a landscape that holds on the screen for 8 seconds, but the director is willing to cut it down to 4. That right there would mean that with simple 24 to 30 FPS math you could make about a hundred specific "DLP prints" and the other prints could use a different long shot like this to get another 100 or so more markings. Simple!
Why am I not working for the MPAA?
Regardless, the bottom line as things currently stand:
Film = good 
Digital = evil 
Of course you can get good copies pointing your camera at the screen, but that's not the biggest threat, IMO. Hackers are generally pretty damn smart, and in reality they WILL break the encryption to DLP and be able to convert the files to standard Quicktimes/AVI's or whatever. They could burn really nice looking DVD's. There is no encryption that cannot be broken. Once this happens then everyone will have to upgrade their DLP's to a new encryption method. And then it will happen again and again. These guys don't have great morals, but they are "whip smart". Who's to say that the team who designed the encryption won't leak out the info? Just 'cause they work for TI or whoever doesn't mean they are trustworthy. Like the RIAA and MPAA want us to believe... "No one is trustworthy".

Another idea is to incorporate an infared signal inside the DLP that projects through the DLP's lens along with the picture. The signal would write the DLP serial number across the picture along with a date and time. The beauty of this is that while no human could ever see it (unlike those CAP code dots), the second a pirate looked through his viewfinder to start videotaping, he would see it and there would be no way to trick the camera not to see it. Just point a remote control at a videocamera and you'll see what I mean. Surely there is some way to make that basic idea work, although I do not know how well it would reflect off of a screen.

I'd make the infrared numbers HUGE. So huge that there is no way they could be cropped out. "Across the entire screen" huge. That would make the pirates say "Argh mateys" and just not tape the movie. Would you rather catch the pirates who do this, or would you rather prevent it altogether? Sometimes I get the feeling that the industry would rather punish than prevent.
Also, about lost revenue. If it wasn't for piracy, do the studios think that people would have PAID to see whatever movies they stole? I think many people pirate just because they can.
Initial encryption (and--ugh!--compression) could be done in the mastering stage by the post house which would put together the entire program. The decryption itself should be done in the projector head, so that all of the data on the wire would be encrypted. As new and better encryption schemes are devised, theatre owners could simply swap cards in their projector heads.
[I won't even discuss the DVD issue here, which is totally different and is set up to deny DVD owners their legally protected "fair use" rights to make copies of the material for personal use under specific circumstances. I strongly oppose piracy, but I won't stand for attempts to infringe upon legally protected rights (at least in the US), either.]
[BTW, for those who are interested in issues of intellectual property rights and the delicate balance between private and common ownership, I can recommend "The Future of Ideas" by Lawrence Lessig. He makes many important points that I agree with, but cannot articulate as well as he does in the book.]



I seriously wonder at just how much piracy affects the film industry. If someone actually wants to see a movie, are they going to settle for some jerky video camera capture? Probably not. Look at this last weekend. Spider-man set box office records left, right, and centre, even though it could be downloaded off of the 'net for free, not to mention not having to wait in lineups. I don't think piracy hurt that movie...
Granted, not all copies are poor quality. The copy of the LOTR floating around is just amazing; obviously a screener DVD rip. Great stereo sound, and amazing picture quality for an SVCD. Yes, I have a copy of it (somewhere), but that didn't stop me from seeing it in the theater nine (9) times. Yes, I am a freak.

"Perhaps I am an exception to the rule when it comes to piracy. I only pirate that which I enjoy (or think I will enjoy)"
You're out of line. If you want to pirate stuff for your own personal use, and you don't see anything wrong with it, then do it. If you get caught with your hands in the cookie jar, you can deal with that as well. Don't expect anyone to approve of it, no matter how noble your actions.

Fair enough. I don't expect anyone to agree with my statements, nor approve. I was just trying to illustrate my point that I didn't believe that Hollywood is suffering as much as they would like us to think.
Movies are better in the theater (most of the time), and I think most people would rather pay to have a nice theater experience than to watch a poor quality camcorder version for free...myself included.
It appears Lucasfilm DID make alterations between the DLP version and the film version of Episode II. Some of the local Star Wars gurus have pointed out that there is at least one very obvious difference at the end of the movie. In the final scene when Padme grabs Anikin's hand, in the film version she grabs his flesh hand. In the DLP version, she grabs his mechanical hand. Apparently there are other differences that are harder to spot too. Anyone running screens of DLP and 35mm film notice differences?
This was probably done to get fans into the digital screenings of Episode II, in the same manor that Lucas will not release a DVD version of Episode 3, 4, 5, and 6 because he wants people to go out and buy HD-DVD (i.e. BlueRAY) equipment when it comes out this fall/next year.
Also, all the pirated versions of Episode II currently available on the internet were done using cameras on tripods with a direct link to the theatre's sound system (which is what is done with most releases). After these are put onto VCD (the first releases were VCD) or SVCD (the new Centropy release (much better quality) is SVCD) there is such a degration of quality that any digital watermark is gone. The odds of a film's pirated release being a Telecline is next to 0 (Telecline machines cost too damn much). These groups use Digital PAL Cameras (25FPS), so the quality is still rather good (depending on how they have it setup).
Note: All items in this post are the truth according to my information and experiences. I have NEVER brought a camera into a motion picture presentation and don't intend to.
I'm not sure what can be done to really stop film piracy. It seems like every effort that is invented to circumvent piracy winds up getting cracked very fast. It's just like those new "copy-protected" music CDs from Sony than can be cracked just by marking the edge with a felt tip marker.
Regardless of what happens, the movie and music industry needs to stop jerking consumers around and insulting them. Rigorous copy protection junk on DVD-V and DVD-A discs serves little purpose when the money making window of film piracy only exists when the film is in the theaters.
And the music industry (particularly the RIAA) has no clue whatsoever when they chisel people for $20 for a crappy CD of mostly unoriginal material and possibly one or two good songs. They were making more money when Napster was around because Napster was a good source of advertising for their product. Jesus, these same morons are paying a fortune in payola to radio stations to get their music played (this is why you seem to hear the same 10 songs over and over and over and over again regardless of music format). Napster was an additional source of advertising. But because they are paranoid, they have shot themselves in the foot marketing wise. I hardly listen to radio anymore since the music is largely so boring and generic anymore. I have to search lots of magazines and internet sites trying to find new bands of interest that are getting no radio airplay. At least with services like Morpheus, I can download a low quality 128kb/s MP3 file and see if their stuff is any good before buying the better quality CD.
The movie industry is flirting with the same bad path. If they hamper digital formats bad enough out of copy protection junk, to where you can't even hook your digital camcorder up to your computer anymore then the whole damned market is going to dry up and they will all lose their shirts financially.
DVD-A and SACD are going nowhere at all since they cannot function on the same levels of user customization and portability as classic Music CD. I can make my own "best of" CDs with no filler material and take it to the lake and pound it out of my boom box as atmosphere for a good tailgate party.
The film industry needs to do what it can to protect its intellectual property, but it better keep interests of customers in mind while doing it.
Theatres will loose their location in american media rather quick, and because the MPAA sees this they want to do everything in their power to keep people in those theatres where they are making $3/person in royalties rather than $1 per household for rentals.

I wonder if it's anything like that horrible copy of Episode 2 that showed up a week prior to release.
It almost makes me wonder, with all of these releases showing up before the actual release date if the bootlegging is occuring at a regular theater.

It just goes to show you how EVIL video is!

Did ayone else see that 5-minue Sprint bit at the beginning? It was hillarious!
Brad, you said "trade screenings." Ours was for Sprint. Were there others that did this also?

What was this Sprint thing?
"A passenger carrying 3,800 pirate DVDs, including 1,400 copies of Men In Black II was intercepted at Johannesburg International airport over the weekend by South Africa's Federation against Copyright Theft, in its latest drive to stem the counterfeiting market which is costing the industry some $6.1m per year."

It's an interesting comparison of the film and record companies' current situation. The point is essentially that the film industry has had great success with DVD sales by giving customers a quality product at a resonable price (which reduces piracy), while the record industry has been hurting by providing customers with what is perceived to be overpriced, substandard products and is thus suffering much more from piracy.
(This isn't to say that film piracy isn't a problem for the film industry, too, but rather that consumers appear to be more likely to purchase the legitimate product when the value appears to be high.)
The print I saw didn't have a cartoon attatched to it. I wonder if it is supposed to be on all the prints? Maybe the Sprint attatchment will be replaced with the cartoon. Anywho, Sprint had a special screening for their employees at our theater Sunday evening. Before the actual movie, there was a guy talking to the audience (obviously the Sprint audience) about selling two of their new phones. Then he and Frank go into a room at MIB headquarters and he practices a sales pitch on one of the aliens. After than, about a dozen MIB's, along with the guy from the Sprint commercials come into the room, but the sales guys dissapears into the counter much the same way the "drivers" of the MIB vehihcles get sucked into the steering wheels. It was pretty funny, but I didn't realize until afterwards that it was only a Sprint thing. The whole time I was watching it I was thinking to myself, "What the phugg is this??"
So were there other companies that had trade screenings besides Sprint? Did everyone recieve their print the way we did - R1-4 onr Friday and R5 on Saturday?
Sprint obviously paid good money to do "Product Placement" along with Burger King. It's a way for a studio to reduce some of its cost and for someone to advertise a product. (Austin Power's Hot Pocket's, Minority Report has a bunch).
When watching the movie, they use a Sprint PCS phone to make calls, a Sprint PCS store was located in MIB right next to BK.
(God, I sound like a commercial)
We received the print the same way everyone else did. Instructions were to remove the commercial, given that we were keeping the print, and to add Chubbs when it came in.
Sony is the worst studio in regards to piracy. Any trade screening that is done, the print arrives 2 hours before show time by courier, built with them watching, shown, immediately torn down with them watching and removed from the theatre.
The worst idea with them was with Spiderman. I had a two print screening on Tuesday before opening. Technicolor said I got to keep the prints, which they were wrong, so I had to break down the two prints for a courier to pick up. Then the next day, a new print arrives for a Wed screening. I do get to keep that one and then on Thurs, the original two prints that I had, come back to me to build up again.
I am going to stop or otherwise I could go on for a whole page.
