Many embedded videos are tricky to download. For example, news sites and Hulu do all they can to hide video files so that you can’t easily find them. If the standard browser plug-ins for downloading aren’t working, try StreamTransport, a free Windows program. I found that it is the only solution for many sites.
Download Flash Videos
If you want to download Flash videos, such as from YouTube, there are many options. My favorite way is to use the Firefox plug-in called Download Flash and Video. It actually can download anything that’s Flash including Flash games.
Install it like any Firefox Add-on by going to Tools – Add-ons – Get Add-ons. Once installed you will see a down arrow at the the bottom right hand of Firefox. It turns blue when there is content on the current page that you can download. It’s simple.
After downloading a video, you can use Handbrake to change the video to another format you might need.
