Hi,

I integrated jw7 in my site. But facing the issue of no video with audio on Firefox,Chrome and safari.
Issue is intermittent.

Here is my snippet
<div id="player" runat="server" style="width: 640px; height: 360px;">&nbsp;</div>
<script type="text/javascript">

jwplayer("player").setup(
{
playlist:
[{
file: 'http://myx-vh.akamaihd.net/z/myxtv/mydiveo/ep13/mydiveo-ep13-,150000,300000,500000,800000,1000000,1300000,1500000,.mp4.csmil/manifest.f4m',
provider: '/CMSScripts/Custom/Global/jwplayer-7.3.6/plugin/AkamaiAdvancedJWStreamProvider.swf',
type:'mp4',
image: 'http://sa.kapamilya.com/myxtv/myxtv/media/myxtv/episodes/eat your words/eyws2_ep04.jpg'
}],
width:640,
height:360,
primary: "flash"

});

</script>

Please suggest me asap.

Thanks,
