What is it?
Real Player allows users to record and download videos from popular multimedia internet sites such as YouTube or DailyMotion by right clicking over the video being played. If the option to download video is missing from Real Player, the issue could be related to the configuration of Real Player, the internet browser being used or other programs installed in the system. The RealPlayer Download and Record Plugin must be enabled in the browser.
