Instructions for Slingbox

Watch DVDs on Reserve... from home!

Note: Slingbox is not on demand or streaming video. The system can only play physical DVDs in real time. Only one person can watch a DVD at any given time, you may need to wait for one to become available.

This service is only available for items placed on Reserve for a class.


  • Before you begin...

    In order to view a DVD from home you will need the following:

    1. A Windows or Mac based PC
    2. A high speed internet connection (DSL, Cabel Modem, T1/T3, etc.)
    3. The latest version of Java, available as a free download here:
      Not sure if you have Java? You can find out by following this link to their verification page.
  • An Overview:

    The library has found a novel use for something really designed for personal use, called Slingbox.  The service is supposed to let you stream what is currently playing on your TV at home, to your PC or Laptop.  We use it to let you watch one of our Reserve DVDs from home!

    4. Configure the SlingPlayer software to connect to the SlingBox with the DVD
    5. Click “Play”
