Ars Technica is reporting that the Doom9 forums has cracked the AACS coding after a WinDVD hole that’s been patched. This is not the first time that they have claimed this. The hacker even claims that it can’t be patched. This used the HD DVD drive that is for the Xbox 360.
AACS is the new copy prevention tool that protects both Blu-Ray and HD DVD disks. Even though it’s very hard to crack unlike the tool used for DVDs, it has been cracked at least 3 times. This crack is shown in this picture.
