I came across this from a Computeractive magazine www.keepvid.com Copy and paste the link from any of the video sharing sites into the address box on the KeepVid site and the site will return a link to a downloadable video No installation is required. Hope that helps anyone on here who wanted to know how to download you tube videos
You need to download an flv player - see link below http://www.martijndevisser.com/blog/article/flv-player-updated hey presto it works perfectly!
