The reason is that keyframes hold a FULL image, whilst other frames are 'deltas' from the image. Some frame grabbers will end up with garbled frames as a result of this.
It doesn't always hold true of course, if the frame grabber is intelligent no problem, but I've seen a number of frame grabbers fall foul of this.
