DVD shows wrong title

[joesmart]

I'm going to apologize if this doesn't belong here, but not sure where else to put it, and I only hang out in this part of the forum anyways. This is somewhat rebuilder related and more due to the fact that I'm curious and not a real problem: I ripped my copy of "The Rock" widescreen using Ripit4me. I noticed that it detected the title as "Birdie" in 4x3. When I started rebuilder, it, logically, showed the same information. I don't know DVD structure like some of the members here, but I'm assuming somewhere on the disc is a section that holds the information about that disc. I take it that this is an authoring mistake on the part of the manufacturer?
:thanks:

That would be the Volume Label. You often seen labels that just don't seem to be related to the title. "Birdie" from "the Rock".... hmm... "Birdman of Alcatraz", I suppose.
