Noticeable Delay Before Video Plays On Computer... Works fine on Ipad.

I have successfully tested my video on Ipad and it works great. However, there is a noticeable delay before the video plays on my computer. It appears that the video is maybe loading in the background before playing the video. Please Help!

Test Page:

Code Used:
<div id="thePlayer"></div>
<script type="text/javascript">
jwplayer("thePlayer").setup({
flashplayer: "jwplayer/player.swf",
file: "videos/lesson3.mp4",
height: "480",
width: "720",
image:"images/video_bg.jpg"
});
</script>

Thanks,

Jared
