Aah, hadn't seen that one. Knob comes off ok, just got to grit your teeth (not round the knob) and pull straight. Feels like it's the wrong thing to do but it comes off ok. Then put small screwdriver or something into hole left by knob and gently ease the plastic panel outwards from the top. You'll find there is a spring attached to back of panel that holds it in. This spring is positioned downwards when replacing, fit lower edge of panel back in pushing panel slightly downwards and it jumps back in ok. Trouble is, you can see the dvd but how it ejects is another question. Slowly, slowly and we'll get there. Why is it when we get these new toys we have to take them apart?
