Home made DVD copy protection - engraved ring

Hello all…

so… there is a home made copy protection for DVDs (movies) that is made with a ring engraving on the writing surface of the DVD (near recording end but not at the end exactly…)

my thought is that its made with a set of dummy files (and the engraving is done on to them) that are put on each disk.

problem is copying of course… all programs report sector errors and stop…

my idea was simply to use DVDDecrypter to get defected sectors and follow the knonw procedure with PSL and PgcEdit… but… DVDDecrypter won’t export any PSL file since it doesn’t recognize that the disk has a sector protection… :frowning:

any ideas would be welcomed :confused:
