I installed Ubuntu 22.04 and typed the following in the command terminal:
sudo apt install ubuntu-restricted-extras && sudo apt install vlc
I accepted the t&cs and it seemed to install OK (no error messages). Unfortunately I cannot play DVDs with either "videos" or vlc. With vlc, I get the following error message on the video screen when trying to play the film Bohemian Rhapsody:
Your input can't be opened:
VLC is unable to open the MRL 'file:///media/chris/BOHEMIAN_RHAPSODY/VIDEO_TS/VTS_01_0.VOB'. Check the log for details.
