Fairmount mounts the contents of a video DVD on a Mac OS X machine as though it were normal filesystem. It is so named because it enables fair use of the content. It does not itself supply DVD reading code, but instead requires that a DVD library from videolan.org be installed separately. Fairmount was originally developed by Metakine and released under the GPL, but they have ceased to develop or distribute it. This version is a fork of their original code.
