what command are you using to mount the cdrom ?
mount /dev/cdrom
will work (with no FS specified, it will auto detect the file system)
maybe you are trying to specify the filesystem type, but forgetting the '-t' flag ?
maybe you are using
mount iso9660 /dev/cdrom /mnt/cdtom
instead of
mount -t iso9660 /dev/cdrom /mnt/cdtom
