BuddyPress.org

It would be unprofessional to say one media plugin over another is better on BuddyPress.org. If it’s not in core then it’s up to you to obtain the additional components to your site. It’s been great that there have been free offerings for a media plugin but I would sleep better buying a paid plugin that I knew was not going to break.

As for no media plugin working with 1.7, 1.7 hasn’t been released. Beta periods are when plugins get updated.
