Something like this, yes :(

Ah, now.. I will supply that, but maybe not before tomorrow evening.

The latter - the DVD-recorder is in a Multimedia-VDR-box, the
desktop with DVD-ROM runs WinXP.

One thing against the faulty-drive-theory is that before I put the
NEC into the Linux-Box, for some days it was running with WinXP+Nero,
where I successfully recorded dash-media. So at the end it might
be the IDE-hardware, which is i865-based (Shuttle XPC). But no, I
won't install XP on that box to try it out :)

In theory both should be usable with both OS. So if growisofs crashes at
the end (of course the drive crashes), the result is a problem for Windows,
and if dvdrecord hangs fixating, the result is a problem for Linux.
There do not happen to exist special linux tools that try to read
media even if some part is not standards-conform, unlike mount?
Need to try if I can open the raw device and read..

Sounds like a good idea, lets see how long until this is implemented
in drives and with media.
But until then, something like automatic power calibration,
if they want in connection with a warning "at your own risk",
could at least give a chance to the user instead of leaving him
out in the rain.. we all know buying media while knowing what
really is in the box is not possible, except for some big brands.
