These videos are streamed and if one is to save them to use with a class in a room with no Internet connection, extra tools are needed. There are a few different ways of doing this, but possibly the easiest is to use the Firefox browser with the Video DownloadHelper extension installed.

When you are on a website with a video, the Downloadhelper icon lights up and spins. Click on the down-arrow beside the icon, and you can select the file and save it to disk. One nice thing about this extension is that the .flv filename extension is there automatically. The file will now play in any FLV-Player software.

Another useful tool is AoA Audio Extractor for saving the sound from a video as an MP3 file.
