By default, DVDFab uses the VSO Burning Engine for burning your ripped DVD’s to disc. If you are running a copy of Nero Burning ROM, you can use it instead by following these steps:
1. Open DVDFab.
2. At the top of the DVDFab window, click the left most button (the one with a sun on it).
3. Select Common Settings.
4. In the left pane of the Common Preference window, select Write.
5. At the top, under Burning Engine click on the dropdown and select Nero Burning ROM.
6. Click OK.
