I've had problems with _some_ UDF discs.  I was just trying to reload my
wife's WLAN driver for ndiswrapper, and Ubuntu could not mount the disc
(needless to say, after reluctantly booting into windows, I discovered
where I'd unloaded them the last time...).

If I try to mount with konqueror:
Dec 27 11:30:58 bella kernel: [70920.980000] UDF-fs: No fileset found
Dec 27 11:30:59 bella kernel: [70921.260000] Unable to identify CD-ROM
format.

A manual mount:
derek at bella:~$ mkdir /tmp/test
derek at bella:~$ sudo mount -t udf /dev/scd0 /tmp/test
[sudo] password for derek:
mount: block device /dev/scd0 is write-protected, mounting read-only
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

I've tried changing the "udf,iso9660" parameter in /etc/fstab to auto (per
https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/44233.  Note,
that shouldn't be necessary as that particular bug should be fixed but
people are still posting to the bug, because they assume that if the
symptoms look the same, it's the same bug...)

And it always makes a hell of a noise, too!

So, I can't help, I can only commiserate...
