At the link below are all the tags we can use here on ATP. Towards the bottom of the list it shows the tags to use for You-tube. You just type the tags in your post as shown there, replacing "Youtube ID" with the ID for the video you want. For example the address for that video I posted is below. The "v=" part at the end gives the video id, so you would put
xUJiD2umYhQ in between the opening and closing tags. That displays the You-tube player embedded in the post with that video already loaded.
