I recently switched to ubuntu(24th) from kubuntu. I hadn't had used kubuntu very much and it was impossible to use my external dvd burner to burn but it could play dvds, cds, and burn cds. after switching to ubuntu I haven't been able to play or burn with it. When i try to go to its directory is says "unable to mount locations" "no media in the drive"

I have a dvd in there and no matter what kind of disc i seem to place in there it never registers.
