Help playing full screen video while loading a map.

Looking for a solution to hide a map load with a full screen movie playing, but not having much luck finding one. I’ve been reading up on media framework and not seeing exactly what I’m looking for. If all else fails I might have to create a loading movie map, but its seem overkill since I’m trying to shave off seconds hiding the map loads in the first place. Does anyone have any suggestion on how to just play a movie while loading in the background?
