Look down the list of directories to find one called TPD, open it & look for another called NCCBEUFNM_EU_20081007 and open this.
I then deleted the directories FRE, ITA & SPA which reduced the image size (shown at the top of the screen) to 4429MB - small enough to get on a single layer DVD. Obviously, don't delete a language you want (I only wanted ENG)
Save the image as the same name you started with & burn to DVD.
That it!
