It might just be a good old fashion dual layer dvd which is created by pressing to discs and glueing them together. These are also known as dvd 9 and most of the movies ship on them.
you can't make a backup of dual layer dvd's containing data. movies can be shrunk by making rhe bitrate smallr.data can also be zipped, but usually has to be unzipped before running it.
