Transformers 2 Problems ImToo Copy Express

I am unable to do a full movie copy on Transformers: Revenge of the Fallen using ImTOO DVD Copy Express. It takes excessive amounts of time and hard drive space. I’m just trying to back up my movie, but I run out of hard drive space to try it with. Anything I can do to make a full DVD copy work with this program?

Not much you can do if you are running out of HD space unless you get a larger HD or else clean that one up some such as deleting some programs to gain more space
