In that case, use Maximum Volume Jobs = 1, and also limit the size of a
volume.
This way, you will end up with several individual files for each of your
backups (it's a lot easier to manage 10 5GB files than 1 50GB file), and
you can also be sure that you will never have two jobs in the same file.
For that matter, I would actually size the maximum volume size so that
you can easily burn each file onto one DVD, just in case. I believe
that's about 4GB.
Also, keep in mind that most likely, only a full backup will be that
size; incremental or differential backups will be smaller (the exception
would be database backups).
