dmesg

you will observe all those errors.

so what can you do?

open the terminal…

sudo bash; # become root
apt-get update;
apt-get install make gcc;
mkdir -p /software/libdvd; # where to put it
cd /software/libdvd
wget https://download.videolan.org/pub/libdvdcss/last/libdvdcss-1.2.13.tar.bz2; # download
bunzip2 libdvdcss-1.2.13.tar.bz2; #unpack
tar fx libdvdcss-1.2.13.tar; #unpack more
cd libdvdcss-1.2.13;
# follow instructions inside INSTALL
./configure --prefix=/usr; # do stuff
make
make install

open vlc, Media -> OpenDisc (Strg+D) and the disc should play now, no restart required.

wasn’t that hard. was it?

but the „know-how“ is crucial.
