Very useful app for PC.
Been using this a lot due to not having expensive, limited mobile data packages, in a poor reception area of 3G, that gets congested frequently. (The Australian country Internet outside of ADSL zones.) YouTube streaming demand most times is too fast, so this has been very handy indeed, instead of using live browser downloaders that are unreliable. I'd donate to one of those.
Sadly, as of today, or could be a few months ago for all I know I'm plagued by "Unable to download this video". Version: 184.108.40.206 installed. I've downloaded a tutorial series previously without problems. It appears there may be an intellectual property block put in place at some time in the recent past.
Good solution to download videos.
Can not be installed.
I never use it and hesitate to begin.
Downloads video without any trouble.
It isn't anything special
