So it looks that for some reason the drive refuses to write to the
second layer.
I can spot in growisofs_mmc.cpp that DVD+R DL get an explicit layer
break position. But this seems not to be true for BD-R DL.
(Especially since BD-R DL have the same profile code as BD-R,
unlike with DVD+R and DVD+R DL which differ. So growisofs is
likely to treat both BD-R types exactly the same.)
Regrettably i cannot affort to do own BD-R DL tests.

This would format the blank medium before writing. I have drives and
BD-R media which work together only unformatted. Maybe it is vice
versa with your drive and media: only formatted.
(Equivalent with cdrskin would be option
blank=format_if_needed
cdrskin does not format BD-R by default.
)
My own problems were with LTH media (aka organic dye).
I cannot spot in the web, whether VERBAT/IMf can be LTH.
But if your media or their sales box show the the letters "LTH",
then you should try to purchase non-LTH for the next test.

Well, i had a BDR-205 for about 9 months until it went bad
with BD-R in general. In the beginning it wrote to LTH BD-R,
then it spoiled those, later it spoiled non-LTH BD-R too.
I could return it to the merchant and got a Optiarc BD RW BD-5300S
in exchange. This one can write a few sessions to LTH before it
finally spoils them. No problems with non-LTH media.
(I also got an older LG BD-RE GGW-H20L which is fine but flatly
refuses on LTH media.)
Given the prices of BD burners and BD-R DL, it might be
smart to buy a cheap new burner if blank BD-R DL media are left
after the next round of experiments.
(The Optiarc burner was sold for 60 Euro ~= 80 USD.)
Please keep me informed about any new insight which you gain
about the BD-R DL problem.
Have a nice day :)
