Alcohol 120%

• One of the top-rated PC DVD duplication programs by CNET's editors, Alcohol 120% reportedly gets the job done quickly but doesn't have the most sophisticated interface. The simplicity of the controls will appeal to some users, and it is compatible with every Windows operating system dating back to Windows Me.
  
  

Nero Multimedia Suite 10

• Nero Multimedia Suite 10 is considerably more robust than Alcohol 120% in that it contains a complete collection of video and audio editing software. While slightly more complex than some DVD-copying software, it comes in handy if you're trying to capture and edit audio or video in addition to copying DVDs.

• "DVD Cloning Software," a website dedicated to testing DVD-copying software, recommends a program called 1Click DVD Copy, which the site says is not only the fastest but also the most-accurate copying software on the market.
