First off, the ISO9660 and UDF formats do _not_ support an "encrypted" filesystem (or a compressed one either).
I don't want an encrypted file system, but a crypted ISO. I don't want anyone to be able to read the contents of the disc...
Secondly, think of .iso as an archive format, with "mkisofs" as the archiver. If you change that format, the unarchiving tool, like "cdrecord" won't know howto read it.
do you mean 'read' when it has to write the iso image on the DVD right? Because I was thinking to _read_ it back with dd.
It's just like compressing something. If the program doesn't understand compression, it won't be able to read the file.
I think I understand your point. I will try the 'iso into an iso' system... bye as
