Sorry, i dont post often and might be putting this in the wrong forum but here goes anyway.
My friend works in an online DVD rental warehouse and he was telling me that theres now a way of finding out if an original DVD has been copied when they have been returned back to them. I dont mean that if they receive a copied DVD back, i mean they can tell if the original DVD they receve back has been illegaly duplicated.
Is that possible. Original DVD’s cannot be written to, so surley theres no way that any information can be passed on to the disc when it’s returned, and also if the dvd was decrypted in a DVD-ROM, then its not capable of writing any information to any disc anyway.
Is this total rubbish or could it be possible, i personally cant see how.
