The Organization for Transformative Works worked with the Electronic Frontier Foundation to help make this happen. You can read more information about that here.Statement of the Librarian of Congress on the Anticircumvention Rulemaking:
The Librarian of Congress has announced the classes of works subject to the exemption from the prohibition against circumvention of technological measures that control access to copyrighted works. Persons making noninfringing uses of the following six classes of works will not be subject to the prohibition against circumventing access controls (17 U.S.C. § 1201(a)(1)) until the conclusion of the next rulemaking.
(1) Motion pictures on DVDs that are lawfully made and acquired and that are protected by the Content Scrambling System when circumvention is accomplished solely in order to accomplish the incorporation of short portions of motion pictures into new works for the purpose of criticism or comment, and where the person engaging in circumvention believes and has reasonable grounds for believing that circumvention is necessary to fulfill the purpose of the use in the following instances:
(i) Educational uses by college and university professors and by college and university film and media studies students;
(ii) Documentary filmmaking;
(iii) Noncommercial videos.
Of course, this only deals with ripping DVDs in the US. Remix/redistribution are other matters.
