DVD-R copy protection
HI!
I know ALL CD copy protection schemes, know and test a lot of copy protected CDs (audio,data,etc...) but today a friend gives me a home movie in a DVD-R copy protected.
I need time to test it but in a fast pass I see 2 sessions (1 with a 1 byte lenght) and I can not copy with DVD burn soft (Alcohol, cloneDVD, etc...).
Is there a new system to protect video DVD-R from copy (like cactus data shield sessions type) ?
This is a not commercial protection (DVD-R with printable surface).
any info about this?
