That doc includes some info I've already posted, but not the DVD info I requested.
Also, I haven't got any at hand at the moment, but I have, in the past, burned multiple sessions to
CDs without imaging the info first. Maybe imaging is only required when you burn with DiskUtility, i.e. without a 3rd party burn utility?
And further, I was appalled to discover how much CD space each individual burn used, making multiple session CDs a poor solution as opposed to DVDs.
Edit: I just made the Tiger, which Rita's running, connection, but (Edit: I believe) my experience goes back to Panther.
