Just to quickly note - That Wikipedia page on which movies contain Cinavia is not completely accurate, for example I can tell you that the DVD releases of 'The Social Network' and 'The Adventure of Tintin' DO NOT contain Cinavia. If you have these DVDs you can check for yourself. Neither one has the required AACS folder on the disk. People post inaccurate things on Wikipedia all the time, sigh...
I find that the DVDFab list here:
http://blog.dvdfab.com/cinavia-protection.html
Is more accurate (100% so, I believe) is updated regularly, and includes more info including Studio name & etc....

EDIT: I am not affiliated with DVDFab in any way, I just find that list a MUCH better source of info on what releases contain Cinavia.
