3outube.com provides an easy way to download YouTube videos to your PC. The video could be downloaded in MP4 or FLV formats. The service is provided for free.
In order to download the video, replace the letter “y” with number “3” of the YouTube video link that you want to download as shown in Figure 1. Finally, choose the format of the video to download (Figure 2).

Figure 1: Replace letter “y” with number “3″.

Figure 2: Choose between .MP4 or .FLV video format.
You can also go to their website and enter the YouTube video link directly inside a text box at the bottom of the page.
I know there are other similar service exist, but replacing letter “y” with the number “3” to download the video is such an awesome idea.
