Since the introduction of the NEW YouTube interface, the old trick of downloading videos through VLC (by first Network Streaming and then copying the URL of the original video) doesn't work anymore; therefore, this add-on has become a must! I donated via PayPal the maximum amount requested of $30, and feel good about it because I'd rather support the DownLoad Plus team than give $11 eleven dollars *every month* to YouTube. So if you agree with my logic, please consider following my example :=) oh, and to those skeptics who aren't sure that the PRO version downloads 1080p videos: guess what, fools? it DOES!
