IE6/7 Freezing during jQuery AJAX request

Question

I'm using the following code to call in some html, and display it. Most browsers seem to handle it fine, but IE6 and 7 freeze up. Unfortunately, the request can sometimes take more than a few seconds, so the delay is noticeable.

I'm also calling Fancybox on success, so that the returned html can have a link that launches a modal window.

Code:

$.ajax({
      url: 'url',
      success: function(data) {
        $('#videolink').hide();
        $('#videolink').html(data).slideDown();
        $("a#video").fancybox({
           'hideOnContentClick': false,
           'transitionIn'       : 'elastic',
            'transitionOut'     : 'fade',
            'titleShow'         : false,
            'scrolling'         : 'no',
            'onStart': function() { _gaq.push(['_trackEvent', 'Event Title', 'Value']); },
           'callbackOnClose': function() { $("#fancy_content").empty();}
        });
      }
    });

Is this the best way to handle the request?

Is your iexplore process using 100% CPU? If yes, then the problem is with slow DOM manipulation by IE. Try commenting out lines in success callback to check if you can find the offending one...
