Civilization IV - How to make a copy?

[magenda]

Please excuse my ignorance since its my first attemp to copy a game...

I`ve rented civilization IV from a videoclub and now I want to make a copy so not only I can play the game after returning the original DVD but also to make a copy,so to be able to install it whenever I want.I searched through gamecopyworld an I found these instructions:

Install the game - Full Installation.
Mount the CIV4_MINIIMAGE_BY_PR1M45.MDS DVD-Image in the latest Alcohol 120%.
Use an anti-blacklisting tool, like AntiBlaxx or SafeDisc 4 Hider, to avoid SafeDisc v4.60 blacklisting of Alcohol 120%.
Play the Game!

My question is:
1)What is meant by "mounting" in Alcohol 120%?
2)How and when (during what step of the process) do I use the anti-blaclisting tool?
3) By doing the above how will I be able to copy the -cracked-game at a DVD of my own,for further use?

Any help is apreciated!
