If you create the iso image using -R instead of the
(usual) -r option to mkisofs, you would keep all information
(permission, owner, etc.):

$ ls -l /misc/dvd/folder1
total 0
-------rwx  1 mk itgroup 0 Jan 17 14:49 007
----rwx---  1 mk itgroup 0 Jan 17 14:49 070
-rwx------  1 mk itgroup 0 Jan 17 14:49 700

However, you risk making a cd that other's can't
read unless they have root permissions.
