I have installed Ubuntu version 21.10 on a friends 12-year-old Gateway laptop.
I tried playing a DVD movie with the Videos software included with Ubuntu, it opens the movie but then it just gives a blank screen, I can click the Pause/Play button but no picture or audio.
I then installed VLC using the command
$ sudo apt install vlc
and looking on this site it says the following needs to be installed
$ sudo apt install vlc-plugin-access-extra libbluray-bdj libdvdcss2
This gives the error message:
Note, selecting 'libdvd-pkg' instead of 'libdvdcss2'
Unable to locate package libblueray"
VLC version is 3.0.16-1
I ran VLC and tried to play a DVD movie, I clicked Media/Open Disk and selected DVD, Disk device: /dev/sr0 - the DVD Title displays at the top header and then closes with no error message. I restarted the computer but the same thing happened. The DVD plays on my Windows 10 desktop using VLC and on my DVD player attached to my TV without any problems.
I live in Australia and purchased the DVD in Australia, DVD region is 4.
I then ran VLC from the Terminal, it also didn't work, here is a screenshot of the error:
I have tried numerous other procedures from searching this site and the Internet but nothing seems to work, so I reinstalled Ubuntu 21.10 and tried again to play DVD movies, the same problem.
Audio CDs play without problem.
Any suggestions about running DVD videos on Ubuntu 21.10 would be appreciated, I have only been using Ubuntu for a few days so please, nothing too technical.
