Turning it on I'm presented with the home screen at glorious 50 Hz (because the 450 setting for the TV is set to PAL and not to NTSC). Inserting a Planet Earth BD, a famous 1080i50 presentation, switches the TV to 60 Hz display! So the player is physically capable of the generating the correct signal, it just chooses not to.
