I would not believe that this is true....
Please show the cdrecord -v -minfo output for such a disk.
If the size is not needed in advance in this mode, then grosisofa _definitely_
does not write in the best mode.

There is no such mode, what are you talking about?
Cdrecord implements the most important things first.....
If there was less FUD from some bad guys at Debian, I did have
more time to code.... but note that I write a lot of OSS software and
I prefer to work on _new_ and important technology. The most important
new technology currently is libfind which causes much more work than
you might imagine. Note that I did write a "find" command from scratch
in one week, but I am spending already more than 50x the amount of
tim in making it a real universal library that works inside star, mkisofs
and as builtin inside "bsh" and "ksh93".
BTW: it would be intersting to knoe why several people did start own
CD/DVD writing software project just to learn what they could learn from
reading my software instead of helping with cdrtools.
