Last fall, the AACS LA announced that it would be doing “proactive renewals” of the AACS encryption keys. While this was intended to prevent people from ripping new Blu-ray and HD DVD titles, the folks at Slysoft have been able to stay one step ahead of the AACS LA. Slysoft is continuing the trend with AnyDVD HD 6.4.1.1. This new version already supports MKB v7 which won't show up on titles until the end of April.
The Advanced Access Content System Licensing Administrator, LLC ("AACSLA") has again started one of its "proactive renewals". Thus leavingmany owners of new high-definition media (Blu-Ray, HD-DVD) in the dark ifthey cannot update their software or hardware players. This new versionof the protection system will be available on new discs released in lateApril, like both Region B BD titles "Alien vs. Predator 2: Requiem" and"Alvin and the Chipmunks".

In response to that decision SlySoft once again updated its system tosupport those new discs and many that are about to be released in thenext few months. All licensed customers of the product "AnyDVD HD" canupdate to the new version 6.4.1.1 free of charge.
If you want to check out the latest version of AnyDVD, it can be downloaded from SlySoft's website. Otherwise, SlySoft's entire announcement can be found here.
