If you are trying to load a movie DVD into Kaffeine or MPlayer, or any other multimedia or video player, and you get the error:
Cannot find input plugin for MRL [dvd:/]
… then creating a symlink via the terminal might be the quick and easy answer to your woes. Basically, you need to link your disc drive’s address to the device /dev/dvd, then all should be good.
Just take note of your drive’s actual mount point, or visible address, which should be something like /media/cdrom0 (and don’t worry if it has the word “cdrom” in it, as it just means any optical disc drive, including DVD burners). Then simply enter the following into a terminal (replacing the drive’s address, if need be), and your DVDs should now open fine:
sudo ln -s /media/cdrom0 /dev/dvd
Command won’t work? Then your mount point doesn’t match the one listed in the command (/media/cdrom0 is quite common, but by no means universal). All you have to do is change it to the correct address; if you don’t know what your mount point is, then read this.
Note that you may need to repeat this after rebooting, so you can just hit the ↑ on your keyboard to save you retyping it in the terminal, or just make an alias for it. If it’s a common bug, it should get fixed soon enough, but at least it isn’t that much of a major deal getting Kaffeine working again in regards to DVD playback.
