Think there are wires running from those PSPs and I doubt its just a mains adaptor
00:11 - 00:15 -- Looks like two wires (one black the other a thicker grey) running from the right hand side of the unit showing the GT4 video
00:25 - 00:29 -- the right hand is suspiciously rigid, could easily conceal wires from behind unit if they run between his fingers.
00:38 - 00:44 -- Another PSP unit behind the demonstrator has a thick black wire connected to it running beneath the table.
1:02 - 1:17 -- Again the way he holds his right hand and constricts the movement of the device is dodgy as anything. Shows the top of the device but no chance of seeing behind.
1:18 1:25 -- Fakest part of the whole demo, not even attempting to slot the UMD in just placing it behind the unit.
