Some factory labels are burned into the DVD
Wrong. All labels on DVDs (and CDs for that matter) are usually going to be a vinyl label that will be stuck to the DVD. In some cases, (such as PS2 games and CD-Rs) the label has the metal sheet with the pits directly underneath it, but stuck to the top of a plastic disc (which is totally cheap, since scratching the top of the CD will render the game unplayable at some point. Other cases, it will be underneath the top plastic layer.
The main difference between a DVD and a DVD-R is the actual medium of both discs. a DVD utilizes a sheet of metal with all the pits and whatnot that are pressed in between two or on top of a plastic disc. When it's stuck on top of a disc, it usually has an adhesive that makes it stick to the plastic and then the label is stuck to the top of that. In other cases (when the DVD is a dual layer DVD), the metal discs are put on top of a single layer of plastic and then another layer will be affixed to the top of that. I'm not sure if they're glued or melted. I'd assume glued.
DVD-Rs, on the other hand, have all the pits created by a ink. A laser will change the shape of the ink.
