RealPlayer Review & Tutorial
YouTube has blocked this program. There is an alternative besides using Realplayer.
It's called "Download Helper", which is available on Mozilla's Firefox.
It carries no viruses, nor malaware.

Download Helper:

The add-on is capable of downloading off any site other than YouTube.
Enjoy!
