About clonedvd2

Hi !
I have been seeing a lot of people talk about clonedvd2 and even found the download for it but before I download it, is there somewhere I can go to find out what I have to do besides download it?
Example: Hook up a vhs player to my pc …and how would I do that?
I have a dvd rewrite on my pc already. I am basically just wanting to know how it works (the clonedvd2) and what I have to do to get it to work.
Thank you
Candis

P.S. what I want to do is transfer all the kid vhs tapes I bought for my daughter when she was little to dvd for my granddaughter. I don’t want to have to purchase them twice.
