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? (Webpage link is sufficient if the= re > is something out there. I couldn't find one.) If you have sufficient disk space, dump to disk. 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.
