网站嵌入优酷视频， 正常嵌入使用如下代码：
<embed src="http://player.youku.com/player.php/Type/Folder/Fid/16572030/Ob/1/Pt/0/sid/XMzE2MTc2NjQw/v.swf" quality="high" width="480" height="420" align="middle" allowScriptAccess="sameDomain" type="application/x-shockwave-flash"></embed>
视频可以正常显示。
将外层包裹p，先隐藏起来。另外写一个链接，点击后再将p显示出来，视频就显示不出来了。
显示白的一片，点击右键，显示“没有加载影片”

我用jQuery做的，没有发现你讲的问题啊。
