By using a service likehttp://clipnabber.com/, you can take videos off of YouTube and host them on your site with this add-on. Unfortunately, it is not currently possible to embed videos directly from YouTube, because Concrete5 does not support a way to add external files. Once it is possible to add something like a YouTube URL to a file set, this will absolutely be possible. In the meantime, the only way this could be supported is by handling it directly on a block level, but the media library is designed to use file sets to make it easier to maintain and much more flexible when videos appear in multiple places on the site. I'm not sure if there's a good way to do this without Concrete being improved

Hi again,

Update!

Yes, you can now use this to organize YouTube videos as well. You'll just need to upload a *.txt file for each video which contains the right URL
