The only difference that I have seen is that the D3 comes with an HDMI cable and the A3 does not. That being said you guys complaining about the titles, you have no appreciation whatsoever for the classics. I’m not talking about the Bourne Identity/300 or the mail-in selection but the 3 titles you pick from amazon.com. As I have said many times before sell the titles you don’t want, thereby making the player that much cheaper.
From that list I could easily pick: The Road Warrior, Top Gun, Trading Places, The Shining, 2001: A Space Odyssey, A Clockwork Orange. Keep in mind that the pre-1990s releases are often the ones that show the most gains when comparing standard def to high def.
