Help -- files no longer plays on W2G

Hi. Three weeks ago, the following video was playing without problem on W2G: J.S. Bach - Cantata BWV 45 "Es ist dir gesagt, Mensch, was gut ist" (J.S. Bach Foundation) - YouTube

When I try to play it now, I get this message: “Important! This website is in no way associated with Watch2Gether. Please decide for yourself whether you would like to open it.” When I do open the video, it plays in a window that is not visible to members in the room–making W2G useless for that file. What is the issue, and does it have anything to do with the owner of the original video?

Thanks much,

I just checked the link. It seems like the uploader has disabled embedding of the video in the video settings on Youtube. If embedding is disabled, the video can not be shown within the player on Watch2Gether but only in an external window.
