If you're an avid downloader of online videos (legal content, to which you have the rights, of course), you might want to tune into RealNetworks' latest offering. The just released RealDownloader is perhaps the quickest and simplest online video downloader for Windows that we've seen. Unlike many of its competitors, when RealDownloader says one-click, it seriously means just one click.

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).
