1. Download YouTube Video using online site
2. Download YouTube Video using free tool
3. Play the downloaded videos or local FLV files using free tool

Part I: Download YouTube Video using online sites
Some free conversion websites can free download of YouTube videos. The following are three of them:

http://keepvid.com/
http://www.zamzar.com/

Step1. Take http://vixy.net/ for example, open the website.
Step2. Visit http://www.youtube.com to find your need video, copy the URL
(e.g., http://www.youtube.com/watch?v=DKhTNNXJIJQ) from the Address field of your Internet browser, or copy the link from the RED dialog box.

Step3. Paste the link at the URL field of http://vixy.net after you open this website, select a conversion format from the “Convert to” field, and click START to download and conversion.

Make sure you turn the "SNIFFER" on, so every YouTube movie can be automatically added to download.

 

Part III: Play the downloaded videos or local FLV files using free tools.

After the video download is completed, you could play the downloaded video files just by click PLAY button without other video players, you can view the play functions from the above picture. This is a very convenient way to play the downloaded FLV videos (or the local FLV files), but the limitation is you could play only one FLV movie each time.
