Addon/Extension/Program to Download 720p or 1080p Youtube Videos?

Tell me any Addon/Extension/Program you know that can do this, for any browser.

For chrome.

 

I believe realplayer provides that funcionality for all browsers.

Not 100% sure though, so you'll have to double check. Last time i used it, whenever a video was present a little symbol appeared when you had your mouse over the video and allowed you to download it.

Now that i told you, you should teach me to script, oh wise simba one

 

Nope:

Tried it, only was able to get it working for low quality, not 720 or 1080

 

My bad they must have changed it recently, it used to put a download button right under the youtube video.

 

I use realplayer, but I don't know if it works for HQ videos.

I found it via some googling.
