Thanks, this will help me, I'll go through it.

Could you please add a comment that my diagnoses are quick shots
in order to illustrate the wide variety of listed problems.

Each such report deserves individual inspection as long as the reporter
is still available, can answer questions, and can make experiments.
I offer to care about them, if they are brought to my attention. E.g. by
the cdwrite list.
Our mileage may vary.

Comment added.

DVD-R and unformatted DVD-RW are normally handled much the same.
But the DVD-RW was blanked in mode fast and you got a honest DVD drive:

/dev/sr0: FEATURE 21h is not on, engaging DAO...

Feature 21h is "Incremental Streaming", a packet write type for DVD-R
and unformatted DVD-RW. It allows multi-session, i.e. the "grow" in
growisofs. Therefore growisofs uses it by default.
Incremental Streaming is always aligned to 32 KiB.

Thanks very much for all the information, it's much more clear now.

Have a nice day
