can't read block device DVD / CD

[maninalift]

When I try to use xine to run a DVD I get the following error:

There is no input plugin available to handle 'dvd:/'.
Maybe MRL syntax is wrong or file/stream source doesn't exist.

VLC produces:

Playback failure:
DVDRead could not open the disk "/dev/dvd".
Your input can't be opened:
VLC is unable to open the MRL 'dvd:///dev/dvd'. Check the log for details.

MPlayer:

No stream found to handle url dvd://

kaffiene (KDE3 version using xine backend) from the command-line:

libdvdnav: Using dvdnav version 1.1.15 from http://xine.sf.net

I CAN play the DVD by setting the Xine engine perameters to read the disk from the mount point (ie folder) once the DVD has been mounted but I cannot read the DVD block device directly.

I have:

libdvdcss
libdvdnav4
libdvdplay0
libdvdread3
libdvdread4
libxine1
libxine1-codecs
xinetd
phonon-backend-xine
phonon-backed-gstreamer

packages installed.

I'm using OpenSUSE11.1 + KDE4 unstable (trunk) + VLC repo + packman repo (64 bit)

This problem has only come into existence recently can anyone help?

... and CDs don't seem to be mountable/playable at all

Oh, I don't know whether this is the problem, the cd/dvd drive does not appear to be listed in /etc/fstab or /etc/mtab:

You are using "KDE4 unstable (trunk)" I suspect it is a bug in this experimental version. Drop back to a stable version. They don't call it the bleeding edge for nothing.

It may be a configuration problem. Create a new user account log in as the new user and see if this account has the same problem. If so see above. If not then there are report back, there are several possible solutions.

I don't think so. I have had the same problem on my vanilla opensuse 11.1 installation. I have lots have all sorts of other problems with my vanilla install so I don't really go near it.
