Subject: unable to mount a CD - iso9660 bug?

Hello,
I have a CD that came with Samsung printer that Linux cannot mount but works 
fine in Windows. The CD is physically OK - "dd" made ISO image without any 
problems. This ISO image is unmountable too. When I force the filesystem to 
iso9660, it mounts but no files are visible:

# mount samsung-bad.iso /mnt/tmp -o loop
mount: you must specify the filesystem type
# mount samsung-bad.iso /mnt/tmp -o loop -t iso9660
# ls -la /mnt/tmp
total 6
dr-xr-xr-x  2 root root 2048 Oct 30  2009 .
drwxr-xr-x 15 root root 4096 Sep 26  2006 ..
# df -h /mnt/tmp
Filesystem            Size  Used Avail Use% Mounted on
/dev/loop0            232M  232M     0 100% /mnt/tmp

dmesg shows this:
ISO 9660 Extensions: Microsoft Joliet Level 3
ISO 9660 Extensions: RRIP_1991A

If anyone can look into this, I can provide a link to the compressed ISO file 
(75MB).
