How do I delete a private video from You tube favorites list?

I added a video to my favorites list, on the You tube website. When I went to my channel page and clicked on the video to play it, a yellow bar appeared, that read, this video is private. How do I remove this video from my favorites list? It is not a video that I put made or put on the website. Thanks.

Find it in there, check beside it, then click ‘remove’, and it’s no longer in your favorites. =)
