I repeated (my understanding of) the guts of what was said, I don't say
it's technically correct. I'll make up my mind about that once I've had
time to study all the tech standards...

Whether such a thing is beyond growisofs et al would depend on the
interfaces available via the drive's firmware. Not knowing the API(s)
provided by burners, what was the reason growisofs at first only worked
with DVD+, and why do the dvd patches to cdrecord only allow for DVD-
burning, but not DVD+?

If there are different recording strategies which a drive must engage
for different media types (if there aren't this is moot), and one of
them doesn't work properly, then that drive is not a good choice for
making lasting recordings on that media type.
