AnyDVD is a driver, which descrambles DVD-Movies automatically in the background. This DVD appears unprotected and region code free for all applications and the Windows operating system as well. With the help of AnyDVD you can watch movies with non matching region codes with every DVD Player Software you like! AnyDVD HD comes with same functionality as AnyDVD, but with additional features for full Blu-ray Disc and HD DVD support, including decryption of Blu-ray (BD+ and AACS) and HD DVD (AACS) movies and removes HDCP. AnyDVD HD costs $80 extra
Only full version updates [like this one] will function as a trial, so if anyone wanted to see if the software was worth the asking price now's the time. It is pricy -- the only real competition AFAIK is DVDFab Passkey, which while cheaper on sale, *may* be harder to buy depending on where you live -- DVDFab is the company that ran afoul of the US courts [so did SlySoft, makers of AnyDVD, but they supposedly resolved the issues].
