There are three common ways available to download/capture/save streaming videos online to your computer:

1. Capture with Web sites
2. Capture with a Firefox extension
3. Capture with commercial programs

1. Capture with Web sites

KeepVid and YouTube Downloader are download-helper websites that allow users to input the URL of a page which contains a video they wish to download. What great about download-helper website is that you need not to download it since it is not a software. All you have to do is to enter the URL source of the video you want to save. The website then begins to convert the video into a downloadable format (such as Mpeg or FLV) which can be saved on the hard-drive.

2. Capture with a Firefox extension

Mozilla Firefox is a web browser whose Video DownloadHelper extension allows the user to download videos directly off websites. This application runs both on Windows and Mac OS X operating systems. What’s great about Video DownloadHelper is that it saves streaming video from over 60 websites and supports extensions like AVI, FLV, iPOD and PSP.

First download and install Mozilla Firefox if you have not already done so. Mozilla Firefox 3.5 can be downloaded at
http://www.mozilla.com/en-US/

When Firefox’s installation is complete, you can now download the Video DownloadHelper extension at https://addons.mozilla.org/en-US/firefox/addon/3006

Click “Add to firefox” button, and then download the extension by clicking on the “Install Now” button in the prompt window. After a few seconds, you will see your new extension in the “Adds-on” window. New extensions will be active after you restart Firefox.

After installation, the toolbar should have the icon located to the left-hand side of your address bar. You should first load the page containing the video stream to use this option. Once you have loaded the right page, click on the down arrow next to your video downloadHelper icon, choose a video format and then save the video. By default it will save it as an FLV format file.

3. Capture with commercial programs

There are available commercial softwares online that require installation. They can be used to download the streaming videos to your computer. Some have the option to convert your FLV format files into Mpeg or AVI files.
