Came back yesterday from vacation, I received the new copy for the mummy tomb of the dragon emperor and Tropic Thunder.
Result : none of them are working.
I had frmware 1.3 (Mummy stuck on loading menu), Tropic Thunder (error cannot play 0x0000000f)
I installed Firmware 1.4 : (error cannot play 0x0000000f)
Can play : Fifth Element, Cars, Iron Man or Spiderman 3
Starting to be really disappointed by this player.....
