Short stutter as movie texture is playing

I'm encountering a dramatic drop in frame rate for about 2 seconds midway through playing a movie texture on Windows machines. This happens with any movie texture, I've got a series of them and they all exhibit the issue. Is there some way to prevent this? It seems like maybe the movies are partially buffered as the scene is loaded, but then when they play instead of streaming from the disk, the buffer is exhausted and Unity must fetch the rest of the clip at that point. Or at least that would cause the behavior, I can't verify this is actually happening. Can anyone confirm this happens to them? I get this behavior on most all Windows machines in both the webplayer and standalone builds.
