Fitting on DVD

first of all, I am using CloneDVD and AnyDVD. I was going to copy a movie EXACTLY but it was 7.51 GB. Blank DVD-R’s are 4.7 GB. What do I do to fit this onto a DVD?

first of all it is a very good idea to read the manual on homesite or just start clonedvd2 and use the help button and read.
it would be a great help.
It helped me.
