Re: LibDVDCSS Not Available?
Actually, the package you need is libdvdread4, and you'll probably also want libdvdnav4 for your DVD experience.
Ubuntu-restricted-extras is a large metapackage that installs both of the aforementioned packages, along with a few proprietary MS fonts, codecs needed for reading and ripping proprietary media files (like .mp3, .wma, .m4a), etc.
Slugslug's advice will install the whole shebang. If you just want the ones for playing DVDs,
If you do that, you can always install ubuntu-restricted-extras for the rest of the stuff later.
$ sudo apt-get install libdvdread4 libdvdnav4
Jane, stop this crazy thing!
