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... > 3.

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...

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.
