When I type AnyDVD in Google, all I get is AnyDVD, at least 5 pages. But aside from that lets welcome our new member to MyCE as SJ so promptly did to our forum and try to explain the differnce between the two programs becuase they are not the same at all. Passkey is a new program and is still in beta, while it is in beta it is free, AnyDVD has been on the scene fro many years ( 8 to be exact) and is an excellent but expensive choice, we do not know what Passkey will cost when it is released for sale. Both are decrypters ( bluray and regular) but AnyDVD will do other things that Passkey will not yet do, maybe soon but not yet. Passkey is free at the moment and AnyDVD has a 21 day free trial so you can try them both for free. I always suggest doing that. Look them both over, try them. Let us know what you think.
AnyDVD is made by a company from Antiguia named Slysoft, Passkey is a completely different program made by Fengtao Software in China. Do not get them confused. Both are excellent programs and yes both are on the fly decrypters for bluray and DVD disks. AnyDVD at this moment has more options but if all you want to do is backup a movie both will do the job decrypting the disc, you will still need a DVD Copy program to burn the disc. With AnyDVD it contains a Ripper that will rip the whole movie to your Hard drive so you can watch it from there at any time. It also protects you from rootkits and such.
Passkey is still in beta and options are being added so we do not know what this program will become when finished or its price but right now its free so take advantage and use it, use them both for free, its a no brainer, see which you like best.
