Flowplayer can play flv,mov,mp4 with fullscreen option, and NOT youtube videos. If you already installed FancyBox plugin, then all we need to do is to place the scripts with a splash image and the link to the video file and make sure the "flowplayer-3.1.5.swf" url is correct on your website. If you want to play flowplayer on an html page, you need to load the "jquery.tools.min.js" (this includes tooltip), if you just want the flowplayer js then download the "flowplayer-3.1.4.min.js" file to the head of your page like this, anyhow, it's either or and not both. I added the jquery noconflict for the tooltip there.
<script language="JavaScript">// <![CDATA[
flowplayer("flow", "/fancybox131/flowplayer/flowplayer-3.1.5.swf");
// ]]></script>
