Well, if you were really concerned, then you would respect that cdwrite
is a *public* list and follow some common sense rules such as
1. If a question/comment is not *directly* related to the subject, do
*not* reply to some post, compose a new message with original subject
reflecting the content.
2. Do not address anybody in person, unless it's absolutely necessary,
e.g. when explicitly commenting on somebody's statement.
3. Review previous threads, explicitly refer to previously read material
[such as manual and web pages, previous posts] and say what exactly did
not work or made no sense.

^^^^^^^^^^^^^^^^^^ It means every word of it. Keep
in mind that growisofs is a front-end to mkisofs, if latter failed to
produce output, growisofs is not the one to blaim:-)

Those are error messages printed by mkisofs. If upgrading to latest
mkisofs version doesn't do the trick, try to reduce the failing folder
to minimum and submit mkisofs bug report to appropriate list (I suppose
this list is appropriate too).

There is very little I can add to "compatibility: caveat lector"
paragraph on dvd+rw-tools page. That little that can be added is
http://lists.debian.org/cdwrite/2003/cdwrite-200309/msg00088.html.

No. It makes little [if any] sense. At least when growisofs calls
mkisofs, it definitely meaningless as kernel [nor mkisofs] support
multi-volume isofs. And when growisofs is invoked to burn a
pre-formatted image, it's more appropriate to have invoking program to
take care of multiple volumes by calling growisofs multiple times. See
http://lists.debian.org/cdwrite/2003/cdwrite-200309/msg00079.html for
example. A.
