I can only see the revenue from this as minimal. My impression is that the people who do download movies are probably the same crowd that rents movies and wouldn't buy movies anyways.
Just another company that wants to profit on royalties.
And speaking of which, this is mid-late in the DVD generation. People should realize that BluRay and HD-DVD formats will have next-to-no piracy when they get released. But I don't see any companies putting all their eggs into the next gen basket right away.
I say, put the eggs in the basket instead of wasting your money on yet another piracy protection program, unless it's 100% teenager-proof. This 97 is a pretty number on paper to PR people, but movies will still get ripped and widespread. The wide-spreading may just take a little longer, but with the way fileshare keeps growing, I doubt it.
