Video files are large, and sometimes require some extra steps to download successfully.  

Be sure you have space for the files on your computer.  Each file name should tell you how large the file is.  You may want to only download two or three lectures at a time as needed.  

A broadband internet connection is recommended to download successfully.  If you do not have broadband, please download one video at a time.  

 Videos are delivered in .mov file format.  This format is supported by most operating systems.  If you are unable to play this format on your computer, try downloading Quicktime.

 Files are currently unable to download directly to your mobile device.  However, you can download them to your computer, then sync your device as you normally would.
