How do I decrypt/shrink/burn DVD's? - avs dvd copy keygen

I have downloaded or purchased many programs, but I have no idea what should be my steps. I have DVD Shrink, DVD Decrypter, CD / DVD burning program, AVS DVD Copy and DVD43. I have no idea what I do not know what to do first, especially since DVD Decrypter tells me it failed. Can anyone help?
