I saw the "Unable to identify CD-ROM format." problem when trying to use a PC magazine cover DVD on my laptop running feisty's 2.6.20-15-generic kernel. Rather than downgrade, try the following:
sudo mount -t udf /dev/scd0 /media/cdrom0/
where "/dev/scd0" is your CDROM device and "/media/cdrom0" is your desired mountpoint
