This is in windows, but i think it would apply to this aswell.. if i try to copy a dvd-ISO or just plain files larger than 4,700,000,000 bytes unto a dvd, it cant really do it, and my media is spewed back out.
So i think you need to listen to Fizikz advice, and get some software to shrink the image (dvd shrink (free)for windows is what i use).
Usually when u rip a dvd movie, the raw data is about from 5-9 GB, and that can obviously not fit unto a 4.7GB disk.
