Change book type (bitsetting) backup DVD-ROM SafeDisc4 games?

I was wondering if changing the book type of the media when backing up DVD-ROM games will affect the compatibility of being able to run off the back up disc? It seems that a game vendor might simple check the disc to make sure it’s a DVD-ROM would eliminate a lot of their piriting issues (as I believe they do now with CD-R disc’s). Any ideas?

i think no copy protection asks for the disc type when reading as this would be/is too easy to fake, for example with the mentioned bitsetting.
