The inputs on the "Play Movie" node, such as playbackrate and settime, should they be able to be modified "live". I trigger the play movie with a FireonStart and from that point those inputs have no effect. Not sure if this is expected behaviour or a bug. If expected why and how can one get around it ... pretty limiting. For example I would normally use playback rate to pause or fast forward under keyboard or mouse control, or settime to jump to chapters or back to the beginning.
