I would like to know is there any video downloader software that I can use to download any type of video from the internet? (evenif it is not youtube video).

I almost forget what the software name is, I think I have use it before to download non-youtube video just by right click the video and press download.

Any clue?

Not really sure how stealing video content has anything to do with Web Development.

You can use a different sort of browser plugins to dowload a various type of stream. However, one which quite familiar both at chrome & firefox is FVD Downloader, you can search, download and install it through chrome web store or firefox add-ons manager.
