I am setting up a Dell laptop with Xubuntu 18.04.2. It seems to be working with wifi and other things, but I can't play a DVD in VLC or the native Parole Media Player. Have no trouble with my other Linux machine running the same build. I've tried all the installations of the Ubuntu-Restricted-Extras, uninstalling and reinstalling it.
I did a test of the codecs and it seems that libdvdcss2 is missing, and I recall that's necessary for encrypted DVD's. Old posts recommended I typed in the commands to mediabuntu.com to get that file - it apparently no longer exists. It is a game sales web site, but perhaps their repository is gone.
I've heard about a paid codec called Fluendo, but when I go to their web site I don't see an individual purchase option - or a price! I'm only wanting to install it in one machine, not a factory run of 5000. It isn't listed in the repositories, of course. I'd be willing to buy it to try to solve the problem if Fluendo would explain how to get it, and it wasn't like $50 or something. Have you got any advice?
