How to locating you tube vidios in posts and pages

The Ultimate Tinymce edit tools include a YouTube insert tool. It works great and even allows sizing of the insert. However, I want to put 3 videos inserts side by side to save space and improve esthetics, and not one under the other, which seems to be the only way this tool will allow. Also I’m unable to indent the location of the insert which is always left adjusted in the post or page frame. Do I need another plugin or something. See the home page of my website, http://livingston-chess.org (second post) to see what I’m up against.
