If you are looking for something to give your family members, almost everyone I know uses the open-source tool jdownloader [0] to download youtube videos.

It's a ponderous java monster but it works great and comes with a huge plugin collection for numerous sites.

The fact that it has a gui makes it really accessibly to non-technical people.

There seems to be talk about AdWare in the installer but I personally never had that problem and you can get around that by downloading the executable .jar.

I know jdownloader. Have been using it in it's early days for 1-click hosters on a separate machine. Don't trust it at all ;)

I don't trust it that much either, but in the end jdownloader gets developed by a company registered in Germany. [0]

If they ever did something really sinister they would be quickly out of business.

Another jdownloader user here. I have similar misgivings about its trustworthiness, but so far I haven't found any concrete reasons to distrust it other than that vague sense of unease. It's just so damn useful though!
