I installed the Fedora 8 Live CD.

It looks like Kaffeine is the only Media player I've got but it won't play DVD movies.

Here's the error message:

xine cannot find input plugin for MRL [dvd:///dev/sr0]

You probably need to enable the livna repo and then install libdvdcss using yum. The steps would be as follows
If you prefer using a GUI to manage your packages, install yumex e.g.

After doing the first command, I get a 'warning':

________________________________________________________________
Retrieving http://rpm.livna.org/livna-release-8.rpm

Do you know what that means.

The installation completed successfully. The warning was about the system not having the livna gpg key (which is actually installed by the livna-release rpm). All you need to do now is enter the second command to install libdvdcss.

Ok, I did that:

But I'm still getting the same error message when trying to play DVD movie:

Try installing xine-lib-extras-nonfree.

Alright, that seemed to do the trick. Everything seems to be working good except for one slight glitch.

If I hit the Stop button in Kaffeine, the DVD movie won't start playing again when hitting the Play button.

I get two error messages:

Obviously, that message isn't quite legit.

When I close that error message, another one pops up:

There is a much longer list of details than what I've quoted here, but you probably don't need to see them all as most of them are a repeat of that last line except for different (diff : 6449) numbers.

I've never seen that type of error using Kaffeine, so unfortunately I can't be of much help. If no one else helps out, try posting in the official kaffeine forum.

I got the same error "don't have permissions" after a couple of reboots
I now have permissions.
I really do think Linux likes to be rebooted. I remember after a rough
night on the town, the next morning after I rebooted I was great to go.
Strange world we live in.

Thanks for your help, reddazz.

That kaffeine forum looks like they have a big spam problem.

But anyway, if all else fails, I can live with the Stop button problem.

And maybe mickeyboa is right. Maybe a reboot will 'fix' the problem. Haven't tried playing another movie since my last reboot.
