According to this article, http://www.computerworld.com/action/...9&pageNumber=1 Canonical has licensed DVD playing software from Cyberlink (PowerDVD),
From the article:At first I had a rant here about the pricing and such, but apparently that's the standard price for the DVD playing version 7. I'm not sure if I know anyone who's paid full price for a copy- tons of OEM computers come with it, and nearly every DVD drive comes with a copy of it.The Cyberlink PowerDVD software sells for $49.95 in the Ubuntu store and allows users to play commercial DVDs on the latest version of Ubuntu Linux, v8.04. OpenGL driver support for graphics hardware is also required.
Something rubs me wrong about this though- I feel ripped off here.
