[jQuery] IE won't show changes made on $(document).ready?

[Frederik Ring]

Hello!

I am doing the following in order to remove those new YouTube-
Headlines on a blog:

$(document).ready(function(){

        $('param').each(function(){
        var oldname = $(this).attr('value');
        var check = oldname.search(/youtube.+/);

        if (check != -1){
        var showinfo = oldname.search(/showinfo.+/);
                if (showinfo != -1){
                        var newname = oldname+'&showinfo=0';
                        $(this).attr('value',newname);
                }
        }
        });

        $('embed').each(function(){
        var oldname = $(this).attr('src');
        var check = oldname.search(/youtube.+/);

        if (check != -1){
        var showinfo = oldname.search(/showinfo.+/);
                if (showinfo != -1){
                        var newname = oldname+'&showinfo=0';
                        $(this).attr('src',newname);
        }
        }
        });

});

This works perfectly on all browsers, except for IE (who knew?). IE
will alter the code accordingly (it will display what I want if I copy
and paste this "new" code into a blank document and view it in IE) but
it will not display the changes made on $(document).ready when I am
just loading the page. Do I have to call this before $(document).ready
or does anybody understand what I am doing wrong?

Thanks!
