Maybe the instructions aren't clear (we can't tell, because you didn't link to them). Maybe you did it wrong.
Download IMGBURN (free) and use that to burn the image to disk. The equivalent command in your current burning program (you didn't tell that either) should be OK, but it's wrong to burn it as a data file or as an video DVD. And with IMGBURN you can't do it wrong.
