I am currently setting up a kodi PVR which is all finished apart from DVD playback.

I have ubuntu 16.04 on my desktop which I set up about a year ago and the dvds play fine on there. When I set this up I did this which has always worked.

    sudo apt-get install ubuntu-restricted-extras
    sudo apt-get install libdvdcss2 libdvdnav4 libdvdread4 libdvd-pkg
    sudo apt-get install libdvd-pkg
    sudo dpkg-reconfigure libdvd-pkg

I have repeated these steps on my PVR (even did a clean install with and without updates) and I can only play non-encrypted DVDs. (None of the ones I have purchased legally work)!

What has changed and how can I get it to work?

I installed windows 10 and libdvdcss for windows on the same hardware (both computers) and all my DVDs play fine (the ones I had time to try anyway). But I don't want to use windows! Everything else works in ubuntu just not DVDs!

I have tried two dvd drives and same problem on both (both work on my desktop PC)
