3outube makes it super duper easy peasy to download a YouTube video to your computer. Just highlight the video’s URL address in your browser and replace the y in YouTube with a 3. That’s it. For example –
3outube.com/watch?v=SjcBcWMLbfY
or
www.3outube.com/watch?v=SjcBcWMLbfY
Geddit? Try it!
This is exactly what I was looking for to store youtube videos on my iPod Touch.
