Looks wrong to me. According to the man page for mkisofs, the Joliet
flag is -J. It's put a space in between - and joliet. I've no idea
what mkisofs will make of that, or what it will try to do.

Anyone who's done "man mkisofs" can guess why.

A suggestion: stop using fancy tools until you get this working.
Learn how to use mkisofs and cdrecord. *Those* work. If your crutch
(cdrtoaster) is broken, as it appears it is, you'll be left in the
situation you're in right now, not knowing exactly where the problem
lies. You're also better off the first time using mkisofs to make an
image to disk if you have the space. You can then mount the disk
using the loopback interface (mount -t iso9660 -o ro,loop cd_image
cd_mounting_dir) and check it out before you burn it.
