I want to burn my friend one of my concert DVD's. It is about 6GB so I bought a dual layer dvd. Since my Macbook only has one drive, I gotta copy it to my mac first. I want to make an exact copy with all the menus, special features, etc. So I was thinking I would just make an ISO image of it to my HDD and then burn that image. What would be the best program to do that?
