Corel has announced its decision to pull the current AACS key from WinDVD, its video playback software. AACS is the protection scheme used in both Blu-ray and HD DVD movies; as previously reported however, that scheme was cracked by diligent hackers, and various movies have begun to seep into illegal distribution. By pulling the key, Corel as well as "partners and other industry organizations" hope to stem the use of WinDVD as an aid to piracy. To continue viewing HD discs through the software, users will need to download an update from their PC or drive manufacturer's website. Corel is so far the first and only company to respond to the AACS crack. [via CDRLabs]
