Assuming they aren't audio, are you mounting the cds from the shell, or through a window manager/gui?
If you haven't already, try this from the shell:
# mount -t iso9660 -r /dev/cdrom /mnt/cdrom
# cd /mnt/cdrom
# ls -la | more
to unmount, jump out of the /mnt/cdrom folder
# cd /home
# umount /mnt/cdrom
