Newb to the site, but not a newb to forums - searched quite a bit and have not seen this particular issue. I've had complete success in the past with Lexus navigation discs, the Lexus Generation 5 hw/sw (also sold as Eclipse aftermarket) had a firmware version with an override feature I like to retain, so I've put together hybrid discs with early firmware and later maps a few times. I got a 10.1 disc, and used ImgBurn to create an ISO and MDS. In the past, all I've needed to do to validate the ISO works is burn a new disc by selecting the MDS and putting a new Verbatim DVD+R DL in my Samsung (TSSTcorp CD/DVDW SH-S182M SB06) burner. I persistently get a layer break error preventing me from writing anything to the disc.
Optimal layer break position must be a multiple of 16
Optimal L0 sectors 2,026,393
Next largest acceptable value 2,026,400

I managed to burn one by manually setting the L0 break at 2,026,400 and I tested it briefly in the navigation unit. It appears to work. Is manually changing the layer break for what amounts to an exact copy expected? Am I doing something inherently wrong causing this problem, or is it possible Lexus is trying to make copying/archiving this data more difficult?
I did try to change the write speed, but nothing seemed to make any difference until I manually set the layer break.
