Yes, I use tarballs with par2 files. par2 files can be created from any
other file or files, and can have as much or as little redundancy as you
like. I usually fill up the medium or add up to 100% redundancy on my
backups, whichever fits.
DVDs already do forward error correction using a similar technology, but
more protection never hurts. ;-)
