YouTube is the best way to watch DSE videos. But if YouTube is not available on your internet connection, you can still watch the videos on this page. They are available in two versions:
- Flash (.flv) version – smaller file size
- Windows Media (.wmv) – larger files and higher quality video
You will need a player such as Windows Media Player, which comes with the Windows operating system. This will play the .wmv format. Another excellent player, available for Macintosh and Linux computers as well as Windows, is the VLC Media Player.
