    'mediabox' => array(
        'class' => 'MediaBox',
        'title' => 'Mediabox',
        'hook_location' => 'profile_left_last'
    )
));

class vB_ProfileBlock_MediaBox extends vB_ProfileBlock
{
    var $template_name = 'memberinfo_block_mediabox';

    function confirm_empty_wrap()
    {
        return false;
    }

    function confirm_display()
    {
        return ($this->block_data['mediabox'] != '');
    }

    function prepare_output($id = '', $options = array())
    {
        $this->block_data['mediabox'] = '
        
        <object width="676" height="386">
