If that is the case then the problem could be simple. Microsoft should be able to change the way the signal synchs up. Since Sony owners have no problem with 720p over VGA it is likely that the 720p signal is not using synch on green. Microsoft would then only need to change the 1920X1080 signal to synch the way the 1280X720 signal does. Of course I have no idea if there are other factors involved but hopefully thats all there is to it.
Not likely... I did my own initial investigation, and the source of the problem is the horizontal frequency.
The XBR2 is looking for a: 1920x1080, 60Hz Vert, 67.5kHz Hor
The 360 is providing: 1920x1080, 60Hz Vert, 66.9kHz Hor
That is 500-600Hz off of what it is expecting. My guess is that the Sony is picky about the horizontal frequency, more than the Samsungs are (since the Samsung is expecting a horizontal frequency noticably lower than what the 360 is providing as well).
