Well I tried this and still go no where.
"cdrecord -msinfo" returned "0,359234"

"mount -t iso9660 -o sbsector=0 /dev/cdrom /mnt/cdrom"
Allowed me to see the files that I normally see.

"mount -t iso9660 -o sbsector=359234 /dev/cdrom /mnt/cdrom"
Returns.
"mount: block device /dev/cdrom is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
        or too many mounted file systems"

When time permits, I am going to find out how these files were recorded.
