Downloading YouTube videos to save

I just discovered a neat site. If you see a video on YouTube you want to
actually download and save to your computer, nook, or pad whatever (for
later viewing)

Go to Youtube and select the video you want.

example:
http://www.youtube.com/watch?vOsrqn...mp;list=UL

Click in that address box and move the cursor to where it is just before the
word YOUTUBE and type the word KEEP so that the address now looks like
this:

http://www.keepyoutube.com/watch?vO...mp;list=UL

Now press enter on your keyboard and it will open a new site and a java
script will run offering to download in various formats and resolutions.
There is also a NON-java method there also I believe.
