Youtube.com is one of the largest video site on the internet. Various types of video such as sports events, news and video tutorials you can download for free from there.
To ease you in to download video from Youtube.com you can use the Youtube Downloader software.How to download: first select the video will be downloaded after a search of the url like this:
http://www.youtube.com/watch?v=UOrcxwKAlOU
Then paste the URL to the Youtube Downloader software and click the OK button for the download.
After the download is complete you can play the video using the various free FLV player like wimpy Desktop FLV Player, Applian FLV Player, or using K-Lite Codec. I personally prefer to use K-Lite Codec because it can also be used to play almost all types of video files.
You can also mengconvert FLV files to other video formats using the FLV Converter.
