Jesus, they put so much effort into "encrypting" this data when it fundamentally needs to be available in a decrypted format for the users to watch it. At the end of the day, there's always the analog hole (or, more likely, the digital hole between the rendering chip and the MEMS array or LCD or whatever other mechanism lives inside the projector). No matter how many convoluted layers of encryption they throw at these things, there's always somewhere you can stick a camera or a few high-bandwidth digital signal analyzers and recover the content with at worst slightly degraded quality.
