Hey ibking, up to a few years ago before a movie was released to the public critics were gathered together in a movie theatre and shown the movie so they could watch and critique it for their newspaper, or tv show. Now the movie studios supply them with pre-release dvds called screeners for critiquing instead. A prerelease dvd screener will generally have a few scenes every so often in black and white with a bar at the top saying PROPERTY OF MGM or whichever movie studio the show belongs to. Some hackers can remove the black and white and the announcement bar before uploading but I have seen lots of movies with it still in. Generally in the scene whichever site gets the dvdscreener up first is the winner, although most of us don't care about that we're just happy not to have to watch the godawful versions taped by videocamera(cams) in the movie theatres, with someones head in the way for most of the movie. I hope this explains it enough.
