growisofs uses mkisofs; you could use mkisofs and not need to insert a DVD.
You could use mkisofs on each user's ~ and maybe find several in one pass.
If these files occur in web browsers' cache directories, you could exclude
those directly: nobody's going to want those restored.
A little more painfully, you could use tar or cpio to create an archive and
burn that to DVD. You can actually burn a tarball to CD or DVD, just as you
would an ISO image. You can't mount it, you read the device node directly to
retrieve its contents.
I personally would look at making a tarball for each user, and an ISO image
containing those. Retrieving individual files is a little more complicated that
just popping the disk into the drive and reading it, but it has advantages
including overcoming your filename problem, (maybe) employing compression.
You could also contemplate a backup server, where you copy users' date
regularly with rsync. Check the rsync home page for Handy Hints.
