Hi, my friend let me borrow a movie and I want to copy it. I usually use clone dvd2 and it says “Cyclic Redudency Check” and it doesn’t work. I usued alcohol to try and clean it but it still doesn’t work. I also used alcohol 120%, but it doesn’t work because the dvd file is 6.87 GB, but the blank DVD I have is 4.7 GB. The DVD can play fine, the computer just cant COPY it. Someone plese help.
