YouTube.com is a popular video hosting website, which streams user uploaded videos in Flash. Since it is streamed you can’t download videos. One of best & easiest hack to download these videos is “kissyoutube” described at “Devil’s Workshop“. In this you need to prefix “kiss” to the video URL & download video in FLV format. Here you need either FLV player to watch that video or FLV converter to convert into a popular video format. It will be so good if you can download video in popular video format like .AVI. Here we go:

1. Got to http://vixy.net/
2. Enter video URL to be downloaded
3. Select video format. You can choose between four formats AVI,MOV,MP4,3gp(for Mobile) & MP3(audio only).
4. It will automatically check for embedded video & starts converting to the format you have chosen.
5. Click download!

It also works for other site like Google Video!
How is that!!
