The Laser was the better method as it could be precise and harder to spot hence harder to replicate.
In the much earlier days when all the s/w came on floppies some disks had deliberate errors in a specific spot either lasered in or in one low tech method a scratch on the disk and if the software install could read that spot it would fail. This is off the top of my head, and is what I believe they sort of do as a copy protection on some commercial DVDs but at the master creation level. Nero should choke when it gets to the bad burn and error out since it is trying to read data from a unburned area. Then After the burn remove the opaque material so it just looks like a bad burn. Possible Magic marker? Put this near the edge where it will be over the area that is filled with dummy data. And what programme can I use to burn the image. If DVD Decrypter is gone and Image Burn has taken over, does image burn elimates the protection on an original DVD if its ripped to the hdd in an ISO format.
You need to put something on the bottom of the disk that will keep the laser from burning properly so as to create a bad burn area. Posted (edited) I am a new member and I was wondering about something. Now before burning and this will take some experimenting to find the right amount to use. One method that could work to defeat a newbie would be have a disk that is not full, then add dummy files to the disk to fill it completely. While the copy protected DVD/Blu-Ray disc is still in the drive, with AnyDVD HD active in the background, click 'Create image file from disc' in the ImgBurn main program window.
