They told us it was bullet-proof, unbreakable. Yet in a mere eight days, a hacker by the name of Muslix64 has managed to single-handedly break the Advanced Access Content System (AACS), the standard that Disney, Intel, Microsoft, Sony, and others developed to protect HD DVD and Blu-ray discs. Or has he? The BackupHDDVD software Muslix64 posted on a Doom 9 forum thread lets you decrypt Full Metal Jacket, Van Helsing, and a few other popular HD DVD titles, but there's still no way of telling how he managed to get a hold of the decryption keys. Only time will tell if Muslix64 is the DVD Jon of the next-gen optical discs.
