When the unit (WD TV Live Gen 3 with latest firmware (1.06.04)) for whatever reason descides to crash, it switches TV mode to NTSC (or whatever strange mode it is). Same thing happened when I installed the new firmware, effectively bricking the unit.
By ripping out the cord, pressing the reset switch for 10+ seconds, ripping out the cord again, sending a prayer to the allmighty I’ve managed to get the machine back on track (this has happened at least 3 times).
My telly says “Unsupported video format”.
But this seems to be quite a big bug, especially as the remote doesn’t have a button to toggle between modes.
