Comment 11 for bug 103173

I did a fresh install of Kubuntu Feisty and found that there were only three packages not installed by default that needed to be installed in order to get DVDs to play. Since Kubuntu mainly uses xine based media players, this should relate to this bug.

The three packages are libdvdread3, libxine1-ffmpeg, and libdvdcss2. libdvdcss2 is not in the Ubuntu repository so it has to be acquired elsewhere. If you don't intend to play encrypted DVDs, you don't need to install libdvdcss2. Additionally, libxine1-ffmpeg requires libmad0 so it will install libmad0 automatically.
