You get the jerkiness because the modem gives the computer the data in bursts. You will quickly get a blast of data, then a pause, then some data, then a pause. The point is that you can make it smooth by distributing that pause among the burst of data when you show it on the screen. The modem will still be sending you data as fast as it can. There is no speed decrease.
