This Auto-Script allows you to download Videos from Youtube.
I saw a script simmilar to this here on the side, but it didn't have the FullHD (1080p) download option wich was sad.
This one was originally an Greasemonkey Script, but it works perfectly with Avant.
Here is a Picture of how it looks like.
As you can see it only uses a minmum of space but has full functionality. It will also only show the links that are avalaible, when there is no HD it will not show a download link for it!
I didn't make this absolutely awesome script.
I did find the script on this site: http://googlesystem.blogspot.com/2008/0 ... files.html
And I tought, man this is amazing, everyone should profit from it.
