Thank you for the writeup - definitely an eye-opener.

Options:

1) Re-enable videos to be uploaded to your own site. Put ads on those. You have enough of a name that you should get at least a trickle of videos which you can use for public (free) parts of the site. Maybe video contributors get free access - X months per video.

2) Get other non-video content up there. Forums, user-submitted articles etc. Change the balance of Youtube vs. non-Youtube content.
