Does the little birthday cake under your name mean its your birthday? If so, happy birthday!
I think you SHOULD be able to copy all files from the dvd to a cd, but I am not sure. Maybe turn off hidden files so you can see them, there may be something else. An ISO, I think, is only a vessel for allowing you to have many files represented as one file for downloading purposes. If you have the filez then you should be good to go.
