The interface is very simple and self explaining. There is a field to select a drive with DVD and a field for the output path.
Select a drive with DVD. If there is the only DVD drive on your computer, it will be selected automatically.
Click the Browse... button on the right. Choose the location where you would like to save your converted video file. Click Ok.
Click the Save to PC button along the bottom of the interface and wait DVD to be copied.
Note: Before clicking the Save to PC button you can set to turn off computer after the process is completed. Just go to Options... and make sure the appropriate box is checked.
