Can you be so kind and tell what exactly is "definitely wrong"? Given
that "definitely wrong" implies "complete opposite is true". Do you mean
that "buffer *overruns* are denoted with "INVALID ADDRESS FOR WRITE"? Or
do you mean that "buffer *overruns* are not handled by cdrecord-ProDVD
transparently"? Or do you mean that "*underruns* are never denoted as
depicted in originating post"? I can agree that my *last* statement can
be classified as "slightly wrong", as "buffer *underrun *can be* denoted
as depicted in originating post" is more appropriate than "buffer
*underrun* *is* denoted." But I can't agree that all of the above is
"definitely wrong."

What is easy to refute? That "buffer underrun protection can't be
switched off in DVD+? Or that "support for buffer underrun protection is
mandatory for Incremental mode"? Or that "buffer underrun protection is
optional in DAO mode"?

We have discussed this already. My experiments with initial SONY 500
firmware has shown opposite, at least with real(!) recording. It most
likely means that it *can vary* from vendor to vendor and maybe from
firmware to firmware (which by the way does *not* contradict that little
documentation on the sunject which is publicly available!). Can you
confirm that you've tested the firmware in question, SONY DRU-510A 1.0a,
in real(!), not test, mode?

We have discussed it too. Being way more practical Incremental strategy
provides for *adequate* compatibility. I have not recieved a single
report that media recorded in Incremental mode was less compatible that
one recorded in DAO. A.
