The newest product from Applied Magic is the USB to DVD Duplicator.  Now you can copy any files to a thumb drive and make copies directly to DVD.  Simply insert a Thumb drive in the front slot, select the file you wish to duplicate and press "start". 

There is no need to make a master for duplication.  Transfer a video file to a thumb drive from your PC (faster than burning a disc) and then start making copies by inserting the USB drive.  If you have a DVD Shop, you could encode the files to a thumb drive while you capture.  This would save several minutes from having to write a DVD in order to make copies. 

   USB to DVD Duplicator is available in 3, 5, 7 9, and 11-Target units
