So true about piracy. Correct me if I'm wrong, but all encryption for DVD has already been cracked. I think if it's sent through the air, this might make it easier to pirate. I think it's unfair making the theaters shoulder all the cost of the digital conversion. Maybe movie houses should take a stand and not convert and see what happens? The old movie projectors are still good after decades of use. I don't know how long the digital projection systems will last. There's always planned obsolescence where theaters are forced to upgrade to stay in business.
