I really cant see the point here. If you want a single layer version why not just download the dual layer and run it through DVD-shrink. But then again, if you are going to do this, you may aswell just be content with the official release.
People on these boards are kind and try to help others out as best they can, but asking someone to make you a single layered version of one of their projects is too much - especially when there is a perfectly good reson for it being dula layer in the first place!
