Just curious, but is the MGEG decoder for these machines the same, or different. Someone who's opinion I trust told me that the HD / 1080i picture was better with the X2 as the A2. I know the build quality is a bit better with the X2 and it has HDMI 1.3, better up-conversion and analoug output, but what exactly is different related to straight HD decoding? Has anyone opened them up?
