Blu-ray and HD DVD are supposed to be highly secure. There is AACS and HDCP, which when enforced make it impossible to copy movie data from a disc.
The premier German computer magazine found now out that you can make copy each frame of a movie by just pushing print screen on a computer. They tested this with the Blu-ray Sony Vaio VGC-RC 204 and the HD DVD Toshiba Qosmio G30 notebook.
Of course it does not make sense to manually sit there and hit print screen. This process could be automated.
CT got Toshiba to acknowledge the copy protection hole and future version of the player software will not have this issue. It is now out there though. All the gory details will be in the print issue of the CT magazine available on Monday.
