growisofs finds my layer break insane
I am having no luck writing a pre-formed video.iso to a DVD+R9
using growisofs v6.1 with specified layer break. Can anyone spot
my error here? Or is growisofs simply going to reject any attempt
to specify a break unless you are doing an exact copy of a DVD?

selected the layer break using PgcEdit, found existing
potential layer break flag at start of a chapter,
1stVOB + 1922283 sectors
making the iso file:
# mkisofs -dvd-video -o /mnt/hda4/MyVideo.iso /mnt/hda3/MyVOBs/
(VIDEO_TS, AUDIO_TS, by the book)
=> MyVideo.iso 7795 Mb (8173432832 bytes)
finding the offset of the 1st VOB data in the iso
# isoinfo
=> 373 sectors
calculating the desired layer break
= 1922283 + 373 = 1922656 sectors
attempting the write to DVD:
# growisofs -dvd-compat -speed=2 -Z /dev/dvd=/mnt/hda4/MyVideo.iso -use-the-force-luke=break:1922656
=> Executing 'builtin_dd if=/mnt/hda4/LikeWater.iso of=/dev/dvd obs=32k seek=0'
:-( insane Layer Break position with respect to dataset size
:-( write failed: Invalid argument
