You can't really and don't have to. It is memory that is dynamically allocated . While you watch the video you are downloading and "buffering" subsequent parts of it. If the playback starts to catch up to the downloading that causes a problem. Pausing the play allows more of the video to be loaded into buffer memory for smooth playback.
