Is there any way to make more than one copy of an unencrypted video DVD without reinstalling and reading the original each time? Starting from the beginning is very time consuming.

There are two ways. One is to enter the number of discs you want to burn in the Recorder Settings window. The other is to choose Save as Disc Image instead of clicking the burn button. When it is done select the disc image using the Image File setting, click the burn button and choose the number of discs you want to burn in the Recorder Settings window that appears.
