From what I've been reading, no device (hd-dvd, bluray, xbox360, etc) outputs 1080p signal through firewire and the Mitsu display only receives 1080p through firewire. You can't connect the source to the TV because no source yet exists that can supply that signal. It would have to be converted from another format, say HDMI, to firewire. No such converter exists either. A lot of people are upset that they have a 1080p capability, but no source outputs in the required format. It leaves MItsu owners up a particular creek and the paddles are back in the bait shop, so to speak.
