This site provides a service that can come in handy to you many times. VideoDownloader.
net offers you the opportunity to download to your computer those videos that are posted in websites. They can be downloaded easily at the click of one button, and directly. However it does carry the disadvantage that this does not apply to all websites, only some. The homepage presents a box where you paste the URL of the video you want to download and click on Download. The site also offers news on downloading videos, encourages you to support them and specifies which are the websites from which you actually can download videos. The design of the homepage is rather dull and could certainly use some colors; however the layout is simple enabling you to browse around easily finding no problems at all. A most helpful service one click away, try it out at VideoDownloader.net!
