libdvdcss is a simple library designed for accessing DVDs like a block device without having to bother about the decryption.
Portability. Currently supported platforms are GNU/Linux, FreeBSD, NetBSD, OpenBSD, BSD/OS, BeOS, Windows 95/98, Windows NT/2000, MacOS X, Solaris, and HP-UX.
Simplicity. There are currently 7 functions in the API, and we intend to keep this number low.
Freedom. libdvdcss is released under the General Public License, ensuring it will stay free, and used only for free software products.
Just better. Unlike most similar projects, libdvdcss doesn't require the region of your drive to be set.
It is legal to install Mint16. Be Free. Whose telling you this FUD?
