Alcohol has an option to change the book-type of DVD+Rs from "DVD+R" to "DVD-ROM". It works fine with my drive (a NEC ND-3520 with modified 3.06bt firmware), but I wonder; why does Alcohol provide for such a function? Is it important for game backups? I thought it's only useful for playing DVD-Video on set-top boxes? Confused... :?

afaik, it's only important for a bunch of standalone dvdplayers which can't
interprete the DVD+R or DVD-R correct - although they're able to focus
the laser to the second layer correct. It's only that those players are build
before the final specs for DVD+R exists - mostly really old players are
affected. To my best knowledge I can't answer if it is already in use by
game protections, however, as many dvd-writers offer you to change
booktype, this check isn't very helpfull imho

Hmm. Given the fact that even when the book-type is set to DVD-ROM when burning a DVD+R (you can't really change the book-type of DVD-R media*) the *media* type can still be detected as DVD+R, it doesn't make much sense for PC drives.

It seems Alcohol provides this option just for the "coolness factor".

* You can, but only if you create a new session on the disc.

Some older standalone players will not play the DVD if it's booktype is not set to DVD-ROM. No "coolness" factor involved.

True, Alcohol can burn more than just game DVD's.

Missed this thread in the change over ;)

Missed this thread in the change over ;)Anyway, my question's been answered. No point in changing book-type for game DVDs. (When I first heard about "bitsetting", I thought this could be used as a "hide ATIP" for DVDs; which doesn't make much sense of course, since no DVD protection tries to read the ATIP. It just asks the drive about the media type. :rolleyes:)
