Things that you need are DVD reader cum writer, source DVD and empty DVD.
First insert the source DVD into the drive which you like to copy.
Mac OS X will try to open the contents of the disk, close any such process.
Now go to Applications –> Utility Folder and open Disk Utility application.
In this application you can see DVD drive listed in the left side bar. Select the DVD drive in which you have inserted the source DVD and click on the New Image button. It will ask you to enter the name of the file and location to save the image file.
