I need to burn an .ISO to a dual layer disc, however, I want to burn the image to the first layer ONLY. The .ISO is only about 250MB. I do not want it split between the two layers. I was curious if Disk Utility can do this? I was needing to set the layer break to Optimal settings (like in IMGBurn), but can't seem to find this in Disk Utility. I sure wish IMGBurn was made for Mac.
