Multiplayer on PlayStation 3 minecraft?

My friend and I are trying to play multiplayer at his house. We can't seem to get the split screen. I turn controller 2 on and press start like i've read everywhere and nothing happens. What are we doing wrong?

Are you using a HD TV connected via HDMI? SplitScreen is only available while using HDMI, also try plugging in the controller and pressing start. If I remember correctly you can disable that feature in the Minecraft settings, so make sure it's enabled
