I haven't messed with profile videos in this new version yet, but I did notice that if you view another members profile page right below their picture in the left column there should be the "actions menu" and in there you should see "profile video" link. That I am guessing should open up the profile video in a new window for the member. I would also expect that you would have to be a member or the member would have to have membership level set to view or use.

I can't see the see more action menu on your site to check, as I am not a member. Non members can not see the action menu.
