Hi :) A little shell history. I merged 6 BD images with a little to spare for the 100GB QL media. But it does not boot (even in kvm, but I tested that too late).
ISO image produced: 47434861 sectors
Written to medium : 47434861 sectors at LBA 0
Writing to 'debian-13.2-QLBD-1.iso' completed successfully.
Run of xorriso program ended without error indication.
Cleaning up temporary files and mount points ...
Cleanup completed.
Merge run ended with success indication.
-- sometime before kvm was run, k3b burned the ISO. I forgot to test it first. :) Burning at 0.7x took 15h. (and it does not boot).
-- this is BD-1 to BD-4.

Note, it's showing "2" as in disc 2 when I combined 1-4. At some stage I ran merge iso for all 6 BD.
