If I may add something in for you guys, I think one solution. I’m using themify.me’s ‘basic’ theme as a framework for a different site and they address the problem in a purely html/css format by doing the following.

1. From the functions.php file, videos links are automatically placed within a div with a class of ‘post-video’ and a transparent background.

///////////////////////////////////////
	// Add wmode transparent and post-video container for responsive purpose
	///////////////////////////////////////
	function themify_add_video_wmode_transparent($html, $url, $attr) {

		$html = '<div class="post-video">' . $html . '</div>';
		if (strpos($html, "<embed src=" ) !== false) {
			$html = str_replace('</param><embed', '</param><param name="wmode" value="transparent"></param><embed wmode="transparent" ', $html);
			return $html;
		}
		else {
			if(strpos($html, "wmode=transparent") == false){
				if(strpos($html, "?fs=" ) !== false){
					$search = array('?fs=1', '?fs=0');
					$replace = array('?fs=1&wmode=transparent', '?fs=0&wmode=transparent');
					$html = str_replace($search, $replace, $html);
					return $html;
				}
				else{
					$youtube_embed_code = $html;
					$patterns[] = '/youtube.com\/embed\/([a-zA-Z0-9._-]+)/';
					$replacements[] = 'youtube.com/embed/$1?wmode=transparent';
					return preg_replace($patterns, $replacements, $html);
				}
			}
			else{
				return $html;
			}
		}
	}
	add_filter('embed_oembed_html', 'themify_add_video_wmode_transparent');

2. The css used against ‘post-video’ looks like this…

/************************************************************************************
POST VIDEO (css for fluid video)
*************************************************************************************/
.post-video {
	position: relative;
	padding-bottom: 56.25%;
	height: 0;
	overflow: hidden;
	margin-bottom: 15px;
}
.post-video iframe,
.post-video object,
.post-video embed {
	position: absolute;
	top: 0;
	left: 0;
	width: 100%;
	height: 100%;
}

I noticed the same thing, it’s stopped working for me as well

After further investigation it turns out that the problem was caused by smart quotes in our joomla content. The plugin worked fine once we were able to clean up our data.
