Nocturnal Lunacy

I've been using imgburn cuz it rocks. But I need to burn an iso file that is almost 8gb but the dvd/r is only 4gb. How can I do this using imgburn, does it have a double disk option? or what? i've looked on the forums and thru the options of imgburn and on google but still have no idea how I can do this. Thank you. ImgBurn.txt
