Its somewhat true that every copy protection can be cracked, but the point is that:
Normal writers cannot burn discs with copy protection features like Securo, Laserlock etc. Companies use special techniques to incorporate these into discs, and moreover those discs are punched ones, nd not a regula burned one.
Even though what Harry Potter said is true, normal drives cannot crack/bypass some protections and its IMPOSSIBLE copy such discs using most of the drives commonly avaiable locally.
I remember some writers[costs insane] from Plextor which boasted that it can burn discs with many copy protection with the provided s/w and it has the feature to regulate the frequency of laser while burning inorder to implement the protections. And the drive was also capable of bypassing most protections as well. It was mainly intended for making copy protected private discs for PS2.
If u want a password protected disc, then ashampoo burning studio can do it.
And the easiest method of copy protection[which only protects against making images of disc] is to carefully make scratch at end of disc. It wont affect most video discs as itll be the credits of movie thats gonna be crappy. Such discs cannot be made image using ny s/w like alcohol, Virtual CD etc if the scratch is gud enuf.
And if u still need more detailed procedure, then just post. ill do it. Im feeling kinda lazy now to type all that stuffs.
