I thought I'd done everything right, reading the guides, checking the forum, buy the correct media.
My first attempt was on a generic blank DVD which reported it's size as 4.4GB, which turns out to be too small. So I waited a week and went to the city and bought 10 Sony DVD-R size 4.7GB discs.
OK now it should work but I still get the following error:

So the problem is not with ImgBurn but my media size!!!!
The question is a borrowed Win7 OS which was on a generic DVD was READ in ImgBurn. How come it wont fit back on a standard 4.7GB disc? Suggestions?
