Hi, just I was looking for the same question. When a user edit a post and put a link to a video (youtube in this case) the video isn't auto-embed by wordpress. But if after than an administrator edit the post in wp-admin and save it (without modity it) appears the video embedded. For users I user subscribers role, can be this the problem ? than it need some capabilitie that dont have ?, I have read about unfiltered_html but this is only need for discover new oembeds not for use knows one like youtube.
@lisa – please check your theme settings. I updated wpuf form with right meta_key, but video not showing up. Also, as admin if i add new port-folio item with video url video doesn't show-up as well? Seems like videos only show up only when you insert them directly to the post?
