To make the burning process smoother and to ensure good usability of the burning results, there are some general suggestions for your reference:
1. Do not run many tasks when copying and burning discs with DVDFab, or you can disable other background tasks that take up a lot of CPU;
2. Update the firmware of your recorder/burner to the latest version and keep it clean;
3. Reduce the write speed to half the rated speed of a blank disc;
4. Use high-quality blank media;
5. Do not run the computer or burn continuously. The temperature of the writer/recorder may overheat, which may cause burning to fail.
