Anyone who's ever tried to watch a DVD on their computer knows that it comes with Digital Rights Management (DRM) software preventing copying onto a computer. The original AnyDVD's function was to remove said DRM's, allowing a user to enjoy a clean copy of their movie. When HD-DVD was released, things got much tougher in the DRM field. DRM's now prevent HD-DVD's from playing back on a video card that does not have HDCP codecs, force a user to watch those pesky advertisements at the beginning of the movie, and force a user to buy a fancy monitor/video card/connector just to watch a movie. AnyDVD HD allows a user freedom from all those problems. This means that any computer with an HD-DVD player, regardless of how HDCP compliant it is, can watch an HD-DVD movie. SlySoft thinks that this
ingenious software is worth $80 USD, with a 21 day free trial. The Inquirer claims that it is worth every penny.
