I know they get leaked but I noticed yesterday that "Rise of the planet of the apes" Blueray is out in torrent sites.I am sure the blueray hasnt been released yet.
How these rippers get their hands on BlueRay versions ?
There are people, such as movie critics, that legitimately receive preview releases of movies before they go out to the general public so that they can be reviewed. These preview copies are often a DVD or Blu-Ray edition of the film. Sometimes the owner of the preview will hand the copy off to a ripping group - if they don't do it themselves - to put up on a torrent site. (That's also why one corner of the ripped copy may be fuzzy - the watermark that indicates ownership is stripped so that no one gets in trouble for it.)
