In October 1999, DeCSS was released. This program enables anyone to remove the CSS encryption on a DVD. Although its authors only intended the software to be used for playback purposes, [2] it also meant that one could decode the content perfectly for ripping; combined with the DivX 3.11 Alpha codec released shortly after, the new codec increased video quality from near VHS to almost DVD ...

It was not an Oscar screener, since the studio forensically watermarks those copies differently.
A unique watermark can be added to the content at any stage in the distribution process, and multiple independent watermarks can be inserted into the same video content. This can be particularly useful in tracing the history of a copy of a video. Detecting watermarks in a video can indicate the source of an unauthorized copy.
The process also involves the correction of color, brightness, and contrast into its original form often consulting the original cinematographers of each films whenever possible. Subtitles and watermarks, if present, are also removed in the process. The process also involves the restoration and remastering of sound.
