I think I've found the source of the bug:
When I open my DVD device direclty over the eject button, the old DVD is still mounted, even if I insert a new DVD.
Nautilus still shows the title of the old DVD in the directory tree.
I assume that the OS still works with the size of the old DVD and can't seek the new DVD to blocks that would be out of range at the old DVD.

Ejecting the DVD via nautilus solves the problem.

This bug was reported in 2012, but the fix is only in Utopic and later...
14.04 LTS still has package libdvdread4 in version 4.2.1-2ubuntu1.
Version 5.0.0-1ubuntu1 in Utopic should be backported to LTS.

Still affects me.

Ubuntu 14.10 utopic
nautilus 1:3.10.1-0ubuntu15
libdvdread 5.0.0-1ubuntu1

This is really confusing for a user! I thought that there was a physical problem with the disc. Thanks to David Seppi for explaining a workaround in the meanwhile.
