When you install RealDownloader, it mingles with your browsers and automatically detects when you navigate to a Website containing embedded videos. This means you don't have to open up the program to use it, resulting in fewer clicks between you and a local copy of that online video. So let's say you navigate to a site like YouTube or Vimeo. Roll over the top-right corner of any embedded video you see, and a small RealDownloader button will pop up. From there, just click "Download This Video" and you're all set--in just one click. If you like, you can then share the original link to your downloaded video via e-mail, Facebook, Twitter, or MySpace.
RealDownloader also lets you play back videos just as simply as you downloaded them, as there's a Play This Video button right in the program. And if you don't have a capable video player installed, it gives you the option to download an add-on player, so you're never left with files that you can't access.
The free version of RealDownloader is available now on Download.com. Meanwhile, if you're interested in RealDownloader Plus, the upgrade is available for a limited time for $29.99 (regularly $39.99).
