Complement report with dvd+rw-mediainfo outputs for *affected* media.
Not fixed-up, not one that actually fails to play. Then apply
dvd+rw-format -lead-out procedure and compare outputs...

Correct, dvd+rw-format works exclusively with rewritable media.

It takes two to dance tango, doesn't it? In this case these two are
recording program and your unit firmware. One side performs the same pas
at the end, but it does not mean that the other side follows as previous
steps were different:-) I mean your impression is correct, but the
reality is not always what we expect it to be... Do submit

Try to record DVD+R without -dvd-compat and then fill it up with
growisofs -M /dev/dvd=/dev/zero...

You probably should say "for DVD-ROM unit to see it," not Windows XP:-)
I mean I find it hard to believe that problems you describe have
everything to do with the fact that DVD-ROM unit is under Windows XP
control. Or can you actually confirm that you can access data in similar
DVD-ROM unit connected to Linux? But in either case answer to the
question is most likely "vendor is most likely is the only one who
knows." Did you check for firmware update, by the way? A.
