If you take a look around the site, you'll now see that where YouTube videos are added to a page, alongside the video is a little DL icon. Click on this and you will be able to download the video and save it as a Flash video file, which can then be played on your computer with a suitable video player. I use the FLV Player from Martijn de Visser, but there are several others - just search on Google to find more.

Make sure you save the file with a .flv extension, eg C:\myvideo.flv

The YouTube Video Downloader page can be used to download almost any video from YouTube. Simply paste in the relevant YouTube video page and it will create a link from which the file can be downloaded. If you know what you're doing, you can convert the videos into AVI or WMV format, and can then edit them in any popular video editing software.

Please do respect copyright, and note that although you have permission to distribute the videos create by me, Nick Gisburne, you do not have permission to re-edit, re-package or otherwise alter these videos. Always ask for permission from the owner if you wish to make use of someone else's work.
