How do you embed youtube videos?

I used to be able to embed youtube videos in O/R posts just by copying the video's URL and pasting it into a post (like this), but now it just shows as the url and not the video (like here). Is there something else I should be doing to get a video to embed like I used to be able to do?

With that second one you have an embed url, use the /watch?v= url and it should work. Differently formatted links throw off the embed plugin. If anyone else has this trouble give a look to the url.

current URL: (with http://You taken off so they don't link/embed)
tube.com/embed/Kav0FEhtLug
Use instead
tube.com/watch?v=Kav0FEhtLug

And then it'll come up

Thank you, Odd! You are the king of the internetz! :hail:
