A software-based company in San Francisco has released a new program that can censor DVDs on the fly. It uses an online movie database of existing "safe cuts," or you can upload your own. Their player then uses these cuts to generate a "cutlist," which plays the movie according to that list in real-time, effectively censoring it. This process does not create or leave behind a hard copy of the altered film, it edits everything in the background, splicing together a new version of the film as you watch it, leaving you with the original movie intact after viewing.

This differs from an earlier lawsuit against a company called CleanFlicks which was upheld in court because it was decided that they caused "irreparable injury to the creative artistic expression in the copyrighted movies," by actually taking your DVD, and creating a "clean" copy of it with all the sex and profanity edited out. Basically, they sent you a duplicate that they created, with none of the bad stuff in it, meaning they physically alter the original movie content on the actual media.

Another company, ClearPlay, provides a similar service through a standalone DVD player that has filters built in to screen out portions of the movie the viewer finds objectionable. Since they don't change the movie itself, they have been safe from lawsuits, so far.
