The mount of new udf dvds fail

Binary package hint: mount

1) Ubuntu:
 8.04 Hardy

Kernel:
ma@ma-desktop:~$ cat /proc/version
Linux version 2.6.24-18-generic (buildd@terranova) (gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) #1 SMP Wed May 28 20:27:26 UTC 2008

All packages are updated to their latest versions

2) Package:
mount 2.13.1-5ubuntu2

3) I expected:
the movie to mount

4) What Happened

A friend burned a movie of me (on a DVD + R) playing football on his Vista box. upon inserting the disc into my ubuntu box, I noticed that it did not automount. A manual mount returns the following:

ma@ma-desktop:~$ sudo mount /dev/scd0 /home/ma/tmp -r
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so

dmesg | tail returned the following

ma@ma-desktop:~$ dmesg | tail

to make a really long, boring story short,
1) Changing fstab entries and command line options do nothing.
2) I downloaded the udftools package with no effect.
3) it IS a legit disc, so this is not a DRM issue
4) the disc is fine - The disc plays flawlessly in Vista, and in hardware players
5) the drive and multimedia software are fine - I can play CDs, ISO dvds, and commercial DVDs perfectly
6) it seems this problem is not specific to Hardy or even Ubuntu. My fedora PC returns the same error, and online research indicates that users of previous versions of ubuntu and other linuxes have the same problem
7) Older UDF discs can still be played

It might have something to do with multisession mode, but I have no way of telling.
I asked my friend if he used multisession mode. He said he "pushed the burn button", and has no idea what the app was called.
