Dont worry about the way explorer shows the file sizes, even when you have created you image you may find many are mentioned as being over 700MB, but when the image is broken down and written back to cdr it will fit onto a 650MB cdr without Overburning or Truncating.

The image files contain extra info for use by the copy program that created it.

Try the proggy's that backitup mentioned and enjoy!
