Hmm, nice idea.

That's because it isn't an isofs, it's a raw dump. Growisofs doesn't understand the dump format and doesn't have a clue where the end of the previous session is. > Any clues to how to get this to work?

Compress the dumps with gzip or bzip2 if you want to fit more on a disk, and put the dumps in an isofs with mkisofs(8). Burn that on a DVD.
