The refresh rate doesn't need to be a multiple of the video frame rate in order to play it smoothly. In fact, games would all be unplayable if this were true because the frame rate is constantly fluctuating between two extremes.
The reason why DVI only gives you 60 Hz is that it reads the EDID from your monitor, and since LCDs are generally designed for 60 Hz only, it limits the degrees of freedom you have on the refresh rate setting. You get more options for VGA because you have less restrictions with an analog signal.
