DVD
Fedora is unable to include support for playback of DVD video because it requires patented technologies and the necessary software may violate the Digital Millennium Copyright Act (DMCA), a copyright law of the United States. The MPEG-2 video compression format is protected by patents under United States law and international treaties. The CSS encryption scheme is a copyright protection measure, and the code that open source players must use to decrypt DVD media using this scheme may violate the DMCA since it can be used to circumvent that protection.

As an alternative to DVD video, the Ogg Theora video format is supported in Fedora. Support for this format is also freely available for other platforms. This is an entirely unrestricted format. While not as common as DVD video, you may wish to consider using this unrestricted format when encoding video. See our page about Xiph.Org formats for more information:
