For the most part the S300 remote works with the S550... Power on, system menu, menu navigation, eject, play, pop up menu. Pressing the pause button and then the slow/step button on the S300 remote doesn't do anything. It just sits there paused. Same thing when you have it playing and press the slow/step button. Nada.
So I think it's a pretty safe bet to say that they have removed the frame advance altogether from the player.
