File segmentation with JW Player
===

I'm trying to make my Video start on a certain point (using time units), so it can be segmented. Here's the Javascript component:

    <script type="text/javascript">
    var so = new SWFObject("/swf/player.swf","player","640","440","9","#000000");
    so.addParam("allowfullscreen", "true");
    so.addParam("allowscriptaccess", "always");
    so.addParam("wmode", "opaque");
    so.addVariable("autostart", "false");
    so.addVariable("stretching", "uniform");
    so.addVariable("file", "Part3.flv");
    so.addVariable("streamer", "rtmp://flash.testsite.com/program1");
    so.addVariable("image", "/images/preview.jpg");
    so.addVariable("skin", "/swf/skin.swf");
    so.addVariable("volume", "60");
    so.write("mediaspace");
    </script>

Is it possible to add a command that points the file: so.addVariable("file", "2012_Part3.flv") to a given time?
