Hi,

No. I do not know about any growisofs flaws with DVD.

(Besides its -use-the-force-luke magic which is reserved
 for those who read growisofs.c additionally to its man page.)

The bug fix has an effect only if you submit a blank BD-R.
It is necessary if one cannot live with growisofs reporting error
and returning a non-zero exit value.

There are rumors that the inappropriate command spoils the burn.
But this is not very plausible because the Pseudo Overwrite
burn is already done when the error happens.

That must have been something else.

Closing the medium should indeed happen with -dvd-compat.
But of course one cannot close DVD+RW, formatted DVD-RW, DVD-RAM,
or BD-RE ... and obviously not Pseudo Overwrite BD-R.

dvd+rw-mediainfo would have told what's up with the medium
after the burn. (It helps to have a copy of MMC specs at hand
when reading its output.)


My offer holds: I am willing to investigate any burn problems.
Be it with my own software or the one of others.
(I must restrict my offer insofar that i will not waste lots
 of expensive one-time media for mistakes which i did not make
 myself.)

A typical first experiment will be to use my own software
with the problematic combination of burner and medium.
This shall not mean that in the end i will urge people to
switch to my stuff. The goal will be to find out what's
wrong with the user's situation and how to possibly fix it.


Have a nice day :)
