How can I see which videos have not been attached to an album? I can see a list of all my albums at http://vimeo.com/patelc75/albums. Also, is there a way to add more than 1 video to an album?
To answer both questions:
(1) Is it not possible to see which videos have not been added to any album.
(2) You can add multiple videos to an Album from the Album's Settings page. Album > Settings > Videos > Add more videos
