loop-aes definitely can mount encrypted CD/DVD usind FAT, EXT2/3 or other
filesystems
I am not sure if it works with crosscrypted isos, too!

That looks the loop device is setup wrong. You don´t need a keyfile or
passwordfile (-K or -p)?
If crosscrypt doesn´t work, i.e. is incompatiple with v3 format of loop-aes
you can still encrypt CD/DVD images with linux.
Anyway, let me know if crosscrypt is really compatible with loop-aes!

Peter
