Hope this is the right forum to post this. I am a huge fan of DVDFab, so this is where I always migrate to.
In any case, I have a home DVD Server that automatically loads cover art and meta-data for store bought discs.
My copies, even bit-for-bit (clones) don’t full the server into thinking they are the originals.
Obviously I’m forced to guess at what criteria the system uses to create a unique ID to cross reference in their database.
One very obvious difference I see is that all the originals show up as DVD-VIDEO discs, where mine show up as DVD-ROM, DVD+R, etc.
Is it possible to write a DVD+R disc that is fully identical to the original? And can you force a DVD-Video bit?
I have a Lacie D2 DL recorder (TSST CD/DVDW SH-S162L USB). The latest firmware does allow booktype bit setting.
The only other thing I can think of is I think I remember hearing that consumer burners can’t write encryption and maybe they use that data to ensure it’s an original and to create a unique idea.
