This depends on the stream bandwidth. Streams nature is that they send exact number of bytes during each second. This number depends on the frames per second and number of bytes per each frame. There is no sence to send more bytes, this is why the speed is limited by the streaming server in most cases. Offline Explorer Pro tries to accelerate the stream, but not all servers support this.
