JWPlayer Dynamic Playlist Not Working IN IE9, IE8, or IE7!

I have just finished a page where users can select up to three different items to see a comparison video. When the compare button is hit, a lightbox launches and a custom playlist is sent to JW Player.

The script works perfectly in FF, Chrome, and Safari. I am using JQuery in addition to the JWPlayer. The video portion of the script does not work in any IE version, 9, 8, or 7. The rest of the script (user interface) works fine in IE.

Any ideas on what the problem might be? FWIW I have a single video file on another page of the site that plays fine in IE 7-9.

Here is what I think the relevant code is. Any help would be much appreciated!

// Load JW Player
jwplayer('video-player').setup({
'flashplayer': '<?php echo $skinUrl; ?>frontend/default/jm_fashira/js/jwplayer/player.swf',
'id': 'player-id',
'width': '720 ',
'height': '406',
'controlbar.position': 'none',
'repeat': 'list',
'autostart': 'true',
events: {
onComplete: function() {
if (this.getPlaylist().length == this.getPlaylistItem().index + 1)
{ // Time To Get Out Of Dodge
$('#video-wrapper').fadeOut('slow');
$('#overlay').fadeOut('slow');
$('#lightbox-close').fadeOut('slow');
$('body').css('overflow-y', 'visible');
}
}
}
});

$('#compare-btn').click(function(event)
{
event.preventDefault();
// Validate
if ($('#compare-form input').length == 0)
{
alert('Please Select Up To Three Violins To Compare.')
}
else
{ // Reveal Lightbox Divs
$('body').css('overflow-y', 'hidden');
$('#overlay').css('top', $(document).scrollTop()).css('opacity', '0.85');
$('#overlay, #lightbox-close').fadeIn('slow');
// Reveal The Video Player
$('#video-wrapper').show('slow', function()
{
jwplayer('video-player').onReady(function(event)
{ // Create The Playlist
var playlist = jwplayer().getPlaylist();
playlist.length = 0;
$.each($('#compare-form').serializeArray(), function(i, field)
{
var newItem =
{
            file: '<?php echo $mediadir;?>comparison_videos/mp4/' + field.value + '.mp4'
        };
playlist.push(newItem);
}
);
        jwplayer().load(playlist);
}
);
}
);
}
}
);

Bump… For any ideas before I rewrite it w/ AJAX.
