The offered programs are not free. Make sure to test their free trial versions before buying.

And there is one more thing. DVD disc can be protected. Most of them come with CSS encryption that can be easily broken by freeware DVD Decrypter or similar programs. The Web-site of DVD Decrypter was shut down. I don't really know whether there are any freeware alternatives.

AnyDVD HD and AnyDVD are great programs. Not only they saved me from CSS Encryption, Region Code, prohibited messages, but also reduced the noise from my DVD drive. They are great, but I don't really think you should buy AnyDVD solely for your DVD conversion.
