High Quality Content by WIKIPEDIA articles! With regard to warez groups or organized piracy groups, a movie is usually released in several formats and different versions because the primary sources used by a group for a particular movie may vary. Pirated movies are primarily released by these organized groups, commonly referred to as scene groups or warez groups. The first release of a movie is usually of a lower quality (due to a lack of sources), and is eventually replaced with higher-quality releases as better sources become available.
