How to check what authoring programme was used?

[grzegorz]

Hi
I have DVD-Video disk (or files IFO, VOB etc.).
How can I check, what authoring programme was used?
Is it possible?

DVD info Pro or DVD Decrypter can give you what little information is stored. Most authoring tools don't leave much of a signature.

Where to look for these information?
I ask for a bit details.
Please.

Check some of the VOB files in GSPOT, sometimes the MPEG data signature (whatever it's called) is overwritten with the authoring software info. Encoders, editors, authorware -- they can all alter that segment of data, and often do.
