Errors and won't play disk

[ChrisOfBristol]

When I try to play a DVD film disk I get " "gst-libav" not found. Not every file will play." I've installed everything I can think of, but aren't Flatpaks supposed to include everything necessary?

It won't allow me to select the disk, just shows me the sound file and the video file.

The Fedora Software application says "Stopped receiving updates", but that might just be Flathub being super fussy about the Flatpak Platform.
