I'm glad that my reply to you in another topic solved your problem to play DVDs:
By the way, I've found that there is a related feature in the "Welcome" application in Ubuntu MATE to activate DVD Playback support. The following post by @franksmcb (Bill), posted in 2019, seems to still be applicable to Ubuntu MATE 22.04 (Jammy Jellyfish):

And here is the text content from that same section (for easier search and reference):
Blu-Ray and DVD Playback Support
Installs libraries that enable Blu-ray and DVD playback in VLC. After install you will need to run
sudo apt install libdvd-pkg && sudo dpkg-reconfigure libdvd-pkg
to enable encrypted DVD playback and you will need to obtain a copy ofKEYDB.cfg
and save it to~/.config/aacs/KEYDB.cfg
to enable encrypted Blu-ray playback [ Remove button ]
