Wow. This topic just saved my day. I have a multiauthor blog and didn’t know that others than admins cannot post video. Stupidest thing ever on an otherwise great platform.
I got it to work with the plugin Role Manager. http://www.im-web-gefunden.de/wordpress-plugins/role-manager/
I allowed “Unfiltered Html” for Authors.
Now it seems to work.
The “Add video / add media” buttons in the editor seem completely useless.
