If you want videos to be shown in a separate line ...

... you can modify the above code as follows:

...
                $output =
                        '<p style="display:block; height:'.$height.'px">' .
                        Xml::openElement( 'object',
                                array(
                                        'align' => $align,
                                        'width' => $width,
                                        'height' => $height ) ) .
                        Xml::openElement( 'param',
                                array(
                                        'name' => 'movie',
                                        'value' => $url ) ) .
                        '</param>' .
                        Xml::openElement( 'embed',
                                array(
