Youtube BBcode no longer works, mass change?

[MarkFL]

I have put together a custom BBCode on my site for embedding youtube videos. What's different about this one is that if the user resizes their browser window, the video dynamically resizes, always maintaining a 10% border to the left and right and always maintaining an aspect ratio of 16:9. I have also wrapped the video player in a container.

Title: YouTube

BB Code Tag Name: youtube

Replacement:

<br>
<div class="video_wrapper MHB_wrappers">
	<div class="MHB_wrapper_header mhb_gradient"></div>
	<div style="background-color:transparent">
		<div class="video-container">
			<iframe src="http://www.youtube.com/embed/{param}?hd=1&vq=hd1080">
			</iframe>
		</div>
	</div>
	<div class="MHB_wrapper_footer mhb_gradient"></div>
</div>
<br>

In your additional.css template, include the following:

.video-container
{
	position: relative;
	padding-bottom: 56.25%;
	padding-top: 30px; height: 0; overflow: hidden;
}
 
.video-container iframe,
.video-container object,
.video-container embed
{
	position: absolute;
	top: 0;
	left: 0;
	width: 100%;
	height: 100%;
}

.video_wrapper
{
	border: 1px solid #BBBBBB;
	-moz-border-radius: 10px;
	-webkit-border-radius: 10px;
	border-radius: 10px;
	margin-left: 10%;
	margin-right: 10%;
}

.MHB_wrappers
{
	box-shadow: 2px 2px 3px rgba(20,74,98,0.5);
}

.MHB_wrapper_header
{
	-moz-border-radius: 10px 10px 0px 0px;
	-webkit-border-radius: 10px 10px 0px 0px;
	border-radius: 10px 10px 0px 0px;
	padding-top: 15px;
}

.MHB_wrapper_footer
{
	-moz-border-radius: 0px 0px 10px 10px;
	-webkit-border-radius: 0px 0px 10px 10px;
	border-radius: 0px 0px 10px 10px;
	padding-bottom: 15px;
}

.mhb_gradient
{
	background: #207498; /* Old browsers */
	background: -moz-linear-gradient(top, #2891be 0%, #103a4c 100%); /* FF3.6+ */
	background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#2891be), color-stop(100%,#103a4c)); /* Chrome,Safari4+ */
	background: -webkit-linear-gradient(top, #2891be 0%,#103a4c 100%); /* Chrome10+,Safari5.1+ */
	background: -o-linear-gradient(top, #2891be 0%,#103a4c 100%); /* Opera 11.10+ */
	background: -ms-linear-gradient(top, #2891be 0%,#103a4c 100%); /* IE10+ */
	background: linear-gradient(to bottom, #2891be 0%,#103a4c 100%); /* W3C */
	filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#2891be', endColorstr='#103a4c',GradientType=0 ); /* IE6-9 */
