Get Full (Encrypted) DVD support in Ubuntu:
---------------------------------------------------------
Need to install the libdvdcss to get support for encrypted DVD's (like retail movies). 
This does not contain the support needed for Blu-Ray (BD) Disks.
Need this package to watch Retail DVD Video on VLC Linux or Rip DVD to ISO for K3B for example.
--------------------------
Get Package: 
sudo apt install libdvd-pkg

Then Build: 
sudo dpkg-reconfigure libdvd-pkg
