Yes, the relevant info is the latter half of section 9.6.6 now.

Sorry for the misinformation! I did actually scan there before writing
the above, but I was reading too quickly and carelessly and my eye
didn't notice the latter half.

By the way, that example reads the dvd twice:
  # dd if=/dev/cdrom bs=2048 count=23150592 conv=notrunc,noerror | md5sum
  # dd if=/dev/cdrom bs=2048 count=23150592 conv=notrunc,noerror > cd.iso

whereas if you know that you do actually want the output file, it will
be quicker to
read it once and then checksum the file like this:
  # dd if=/dev/cdrom bs=2048 count=23150592 conv=notrunc,noerror > cd.iso
  # md5sum cd.iso
