I can't seem to find a way to center a Youtube video in a post anymore.  In IPB 3.x, I could just highlight the link and hit the "center" option and voila!  That doesn't work now.  And, since I can't find a way to change the editor from rich text to basic, I can't try it that way either.  Is it even possible to center a video in a post?  If so, what do I need to do?

The video sits in a DIV container (class name “ipsEmbeddedVideo”) which is a block element taking up the full width by default. You could change its behavior globally via CSS, but you can’t just change its alignment with the text editor options, since it’s not an inline element.
