When burning with DVDFab, there is a button marked "Burn Again" that appears at the bottom of the window after the burn completes successfully. Next time, just click that. If you have VIDEO_TS folders on your hard derive, just use DVDFab's Write Data mode and select the VIDEO_TS folder as the Source. The blank media must be able to hold the folder without any compression. If you are new to DVDFab, read through the Tutorial. The red link below in my sig will take you there.
