Muon Package Manager gave me the warning that the source of libdvdcss2 could not be verified. I know it was available from Medibuntu, and as I understand it, Medibuntu has gone away. Is there another repository for this library? Thanks.
To install libdvdcss2 there is a script included in libdvdread4.
So first install this package with either muon/synaptic or via commandline
sudo apt-get install libdvdread4
and execute the following in a terminal
This will download and install libdvdcss2
