The burning speed depends on the length of the source file, the output settings and the computer configuration. Here are some tips to improve the burning speed:
1. It is advisable to select Fit to disk instead of High Quality for the output DVD. The higher the quality is, the more time the product will take to burn it. However, there will be some quality loss.
2. As the recording function is very CPU sensitive. Closing other unnecessary applications is advised. You can press CTRL + ALT + DELETE on your keyboard then select task manager to close other unnecessary applications. Make sure you save any work before you close an application.
