The amount of effort in setting up two perfectly synchronized video projectors would be extreme; it’s worse than useless if they’re not preciseley matched. (Seriously, how could you not think of that? ) Also, now note that that free movie on the internet is going to cost you two projectors, two DVD players, and, as noted, not a snowball’s chance of actually getting them matched up right.
I’m willing to concede that some dude might set up a highly technical and carefully rigged homebrew home theatre just to prove he can do it. Heck, he’s the guy who’ll have also cracked his second copy of the original device open and figured out a way to intercept the digital signal to the projectors! He’ll have made a perfect copy of the movie; he’ll have defeated the system!!
Good for him. The important thing, that the moviemakers care about, is that
I don’t claim I’m perfect (except between 11:15 and 11:17 pm on even thursdays, right then I’m really hot stuff) and yes, a really, really motivated guy could manage to succesfully view his analog copy the movie. He might even manage to hit the play buttons on his remotes simulaneously again and watch it a second time! But unless you come up with a better trick than the ones you’ve mentioned, this system has still achieved the aim of being too inconveneint for the average consumer to bother trying to crack it. Which is really all that matters.
