I think the parent is referring to libdvdcss, which is the library that cracks the DRM encryption on the dvd. Without it you wouldn't be able to skip unskippable parts, nor even play the dvd using non-authorized dvd players like vlc. libdvdcss is developed by the videolan project, which is the umbrella project for vlc.
