DVD ID?

Are there any signatures are ID-codes or anything weird and possibly identifying that Nero puts on DVDs (or in DVD files) when I encode/burn them?

Analogy: Adobe's PDF files contain a string detailing the authorship of the file, which can be accessed in Acrobat.

Nero doesn't do shit to you.

The analogy is not valid because Adobe is known to be a producer of shitty file formats and software to browse them. Just don't use portable drm format files, use text/plain.
