So we could do more experiments without media waste.

The command lasts very long and finally fails with SCSI error 3,0C,00
which indicates a write error.

This is a problem between drive and medium (possibly between drive
and any DVD+R DL media).

You could try to hide the image size from xorriso and thus avoid the
But i expect a write error with the first WRITE command then:

  cat /home/axel/Videos/USA/Birth of a Nation.iso' | \
  xorriso -as cdrecord ...options.except.path.of.iso.image... -

The dash "-" lets xorriso read the image from standard input.
Do not use options --grow_overwriteable_iso or -isosize.
They would let xorriso inspect the beginning of the ISO image
in order to learn its size. If it knows the size, then it will
issue the RESERVE TRACK command.

(Less tricky would be to use a newer xorriso, which knows command
   -write_type "tao"
 resp. does not ignore -as cdrecord option -tao.
 But even the version 1.2.2 of Debian testing is too old for that.)

Have a nice day :)
