For any kind of Videos there’s YouTube: http://www.youtube.com/
To download videos from YouTube and any other site :
Get Firefox from http://www.mozilla.com/en-US/firefox/
And then install the Download Helper extension from https://addons.mozilla.org/firefox/3006/ or this one Video Downloader https://addons.mozilla.org/firefox/2390
It works great for me.
Since the videos are in the .flv format you need to get a flv player. You can get a very good one (and completely free ) here http://www.download.com/FLV-Player/3000-…
If you want to convert them into another format ( mobile phone, iPods, mp4…and anything else) use this awesome free program called Super http://www.erightsoft.com/SUPER.html
Also you can use this site http://javimoya.com/blog/youtube_en.php and copy/paste the url’s from the page with the video there but personally I’d recommend using Firefox
Firefox is the best !!!
And for movies and anything else use http://www.torrentportal.com/ and http://www.bittorrent.com/ and http://www.torrentspy.com/
To download from this site you need a torrent program like these :
BitComet http://www.bitcomet.com/ or
Azureus http://azureus.sourceforge.net/
