RealPlayer SP for Mac is a free media player that comes close to mimicking the features and interface of its Windows cousin. While many users can get by with the bevy of other excellent free media players available for the Mac, RealPlayer SP does offer some nice extras in an integrated interface, such as the ability to download streaming video through a companion app (the RealPlayer Downloader) and modify it for specific outputs or devices with another companion app (the RealPlayer Converter). If you also install the RealPlayer Download Agent, the RealPlayer Downloader will automatically detect when you're streaming DRM-free video (such as from YouTube) in your browser that can be downloaded -- and you can then download, share, convert, or copy the video to iTunes.
Unfortunately, in keeping with the tradition of RealPlayer staying a step behind on the Mac, buggy behavior isn't unusual and the app's best feature, the Downloader, sometimes doesn't function at all.
It's social. It's portable. The new RealPlayer SP for Mac lets you download your favorite online videos from thousands of Web sites and transfer them to your iPod, iPhone, iPad, BlackBerry or other favorite device, quickly and easily.
