Bad luck, that I still have 2 batches of 699MB CD-Rs (stamped '700MB', different brands). The 3.6 ISO almost fills the CD-R completely (only a few 10KB left). The burner didn't complain, but I got read errors when Knoppix started mounting the big system image. Two out of 3 times it recovered and worked properly throughout the remaining session. I thought something was wrong with my burner. Finally I tried a CD-RW with true 702MB capacity and this _worked_.

Obviously the CD blank must be 1-2MB larger than the ISO file. This problem had cost me hours and an extra download. A small note in the CD burning instructions might be useful.
