Vista - dvd decrypter

i know there are alot of different versions of dvd decryptors, but i downloded mine from the internet, and for some reason or another it wont decrypt the whole move, i dont know whta the settings should be on, what rate or type it should decrypt, does any one have any ideas, also i got a dvd ripper, but it only rips the audio and not the movie, ia any one familiar on how to use this

Dvd Decrpytor was shutdown years ago for allowing the illegal copying of dvds, Its now called ImgBurn but without the decryption You should know how illigal copying is under Australian laws

Forum Rules do say no Illegal Discussion so thread closed
