YouTube made some changes (yet again yesterday), which caused issues with downloading videos through RealPlayer. The good news is we’ve already updated RealPlayer version 24 to handle this — it’s working again!

To fix it, just over-install RealPlayer from www.real.com. No need to uninstall — just run the installer and continue when it says RealPlayer is already installed. If you’re on version 22 or version 20/20, simply Check for Updates to install the latest Video Downloader. When updating, uncheck "New RealPlayer 24" and click "Other" to download only the Video Downloader. Instructions to update Downloader (version 22 and 20/20 only)
