To add to goodsound's comments, I'll make this observation: our daughter has learned not only that the remote control makes the system change but that pressing buttons on it at random can mess it up. If she wants to watch something other than what is on or if the remote is in the way of something she's doing, she will very carefully bring me the MX-700 (holding it underneath like a plate with the buttons up and safe from accidental mashing) and hold it out for me to take. This did not used to be the case, as button mashing was too much fun in its own right - which is why the toy basket on the hearth includes two or three old remote controls with the batteries removed.
