Ian:

Thanks for the reply.  It looks like you are experiencing a bit different
problem on your machine.  At least your disks are mounting.  I did install
the libdvd-pkg just to see if anything improved, but it did not.  I will
file a bug report against the mount(1) command and see if the developers
are aware of the problem or can distinguish between a software and hardware
error.

Just curious what makes you think this has anything to do with Xubuntu
vs. Ubuntu?
