I’m a 20 year Linux veteran. I’ve been using the KDE spin of Fedora 28 workstation for a while now, and I just discovered I can’t play commercial DVDs!
Now it seems to me this is a pretty important thing to do. I’ve already installed a bunch of packages and still I can’t get VLC, MPlayer or Kaffein to play my Johnny Depp movie inserted in my blu-ray/dvd drive.
Now I installed various packages that were recommended in various Fedora forums and I still haven’t got any luck whatsoever. So that’s where I am now and I’m going to document in this article where I go from here.
I’ve started a fresh login to my KDE Fedora spin. and now I’m on my main screen. I have a DVD inserted in the drive and I’m going to click on multimedia and Mplayer to see if I can’t play it.
Well I didn’t get anywhere with that so now I’ve started the program Kaffeine. I click on 4 play DVD and I get a title called The Ninth Gate which is a Johnny Depp movie that I have in my drive. The title goes away and I left of the black screen and nothing playing so I close out that program and next Sun going to try loading VLC media player.
So now that I have the VLC media player on screen I click on media and then I click on open disk and I have a selection DVD, Blu-ray, audio, CD, Etc and since it’s a DVD I click the DVD option and then click play. Naturally, nothing happens.
Someone on a forum said I needed to do this.
su
yum install gstreamer1-libav gstreamer1-plugins-bad-freeworld gstreamer1-plugins-ugly

I did. No help. Someone said I needed

sudo dnf install libdvdnav

No help.
Now wait. I just remember maybe I should install xine, another media player. So I did. sudo dnf install xine
So now I start xine from the command line and the program starts. I click on DVD.
Alas. I’m now back inside Kubuntu.
