I wouldn't expect the stage monitor view to actually display videos as they run, but it'd be really nice if in addition to the name of the video file that is playing, the stage monitor also showed the playback time. Something like "0:45 / 2:52" just so folks up front have some sense of whether the video is going to be 10 seconds or 10 minutes long and if it's halfway through or almost done, stuff like that.
