Good mod but do not work with multyservers. For more info go to class.video_player.php and you will find it. :D
something like this i think
Code:
        if ($this->video_info['video_server_id'] == 0)
        {
            $file = VSHARE_URL . '/flvideo/' . $video_folder . $this->video_info['video_flv_name'];
            $video_id = $this->video_info['video_id'];
        }
        else
        {
            $sql = "SELECT * FROM `servers` WHERE
			       `id`='" . (int) $this->video_info['video_server_id'] . "'";
            $result = mysql_query($sql) or mysql_die($sql);
            $server_info = mysql_fetch_assoc($result);
            $video_id = $this->video_info['video_id'];

            if ($server_info['server_type'] == 2)
            {
                $uri_prefix = '/dl/';
                $f = '/' . $this->video_info['video_folder'] . $this->video_info['video_flv_name'];
                $t = time();
                $t_hex = sprintf('%08x', $t);
                $m = md5($server_info['server_secdownload_secret'] . $f . $t_hex);
                $file = $server_info['url'] . $uri_prefix . $m . '/' . $t_hex . $f;
            }
            else
            {
                $file = $server_info['url'] . '/' . $this->video_info['video_folder'] . $this->video_info['video_flv_name'];
            }
        }

    }

    function youtube()
    {
      echo 'Video download disabled';
    exit();
    }

    function revver()
    {
       echo 'Video download disabled';
    exit();
    }

    function metcafe()
    {
        echo 'Video download disabled';
    exit();
    }

    function embedded_code()
    {
        echo 'Video download disabled';
    exit();
    }

    function flv_url()
    {
        global $config;
        $file = $this->video_info['video_embed_code'];
        $video_id = $this->video_info['video_id'];
        $video_folder = $this->video_info['video_folder'];
    }
