Burn disc from an existing DVD folder or image. The Source must be your HDD, not a DVD drive; the Target can be a DVD writer or you can use this mode just to convert a DVD folder to an ISO by clicking on the ISO icon in the target area. Remember that this mode calls the burning engine immediately and does not process the Source at all, so it will not apply compression. Your files/image must be able to fit on the blank media you have selected and be ready for burning.
