There are a lot of way to download YouTube video, for example, video downloader addon of Firefox, keepvid.com, and I also recommend Leawo Free YouTube Downloader as it can download almost all Flash video from the Internet.
Internet Download Manager and Firefox IDM plugin is the best option to download youtube vides.... not only youtube videos... using this you can download all flash video contents in anypage
u should try IDM(internet download manager).after installing this a link will show for every video and audio u can download on clicking on it
lol..Clipta tool bar is better and best dude...just open a video which u need to download and tool bar will capture it..sites may sometimes annoy you.. CLIPTA FTW..
Internet Download Manager is the bestm, you can download every youtube and all video and it is very fast. i download many of video with it.. it works for me..
listen bro. get the Ant Video Downloader. i use it i think it's the best. you can download a video from any where. first play the video and as soon as the video plays you can hit download to get it. works on any site on the web. with 7 million downloads you cant go wrong. hey you can even download movies from my site.
