Were you able to open it? If so I don't get the problem.
I tried to copy the window, but copy and paste works differently with the different Mac OS I have now. It's very easy if I can drag and drop, but becomes complicated if I try to do it any other way. And I'm just too frustrated to keep on trying.
That's a different problem that is related to your MAC and not IHub.
I can click on the video then the YT link and it opens in a new window and reveals the link you can copy and paste.
