I just donated $30US for the Pro version, because I want to support this plugin and keep it alive. I review music videos (for fun) on my YouTube channel, and I need to be able to download good quality versions of each one to use in Adobe Premiere (30-40 sec excerpts). This is not only blazingly fast, but it *works*. I'm getting tired of YouTube changing something behind the scenes and ruining the ability to download videos, breaking every plugin out there. $30US one time, hell even once a year, is a small price to pay for this service.
