RealPlayer "Unable to download"

Incase you have installed RealPlayer Splus and are facing with "Unable to download" error while trying to download videos online. Please read on.

I am not sure as to what's the fix for the windows/firefox option and why trying to press "Download This Video" displays gives this error "Unable to download".

But the workaround is using RealPlayer to download the online videos.
Try:
File->Open-> "Enter the web address/ the youtube address" ->OK

When the webpage opens inside the RealPlayer window, you see the "Download This Video" here too. Just Click this and it will download the video.
