Good.  This mean there is a problem *specific* with Ubuntu (no hardware
failure).

Okay.  The last two lines tell us that the Linux Kernel itself didn't
recognize the disk.  In other words, the Kernel can't read the TOC
(Table Of Contents) of the DVD and there is no problem with other
softwares (i.e. gnome-volume-manager, mount, or pmount).

The above result to be expected when the Kernel can't read the DVD.  How
can you mount something you don't see?!!

Here's my last shot: Are those DVD(s) self made?  There is a bug in some
Kernels (including the one in Hoary) that prevents the Kernel from
reading some multi-session DVD(s).  If that's the case, then the
solution would be:
      * Use IDE SCSI emulation for the DVD.
      * Compile your own Linux Kernel.
      * Wait for Breezy to be released.
      * Don't wait for Breezy to be released, and start using it know
        even of it's not stable. (This is *NOT* recommended!)
