It is really pretty easy to include a video in your post once you know how.
If you click on the second button in the second row in the toolbar in the post editor it will enter a code into your post.
you then need only insert the "Share Code" (for example "http://youtu.be/NIv3W1vUoKU") between the embed tags
See the attached image for a look at this post in the editor...
