Gennum VXP and Realta HQV are the only chip out there bringing everything to 1080p first then downscaling to 720p. Everything else out there is doing 1080i to 540p then 720p. That's why the difference is not "big".
I'm sure you already understand he difference between 540p and 1080i. Your comment here confused me. To say that the DAC's are scaling to 1080i first is interesting. 1080i looks the same as 540p to the DAC's. In ,ost cases it is what your end product does with it that will decide if interlacing is to take place. Therefore, if you are correct, The projectors will take a 540p signal (which can be displayed as 1080i or 540p) and up-scale it to 720p.
Now, as for difference, not much w/ the exception of high chance of artifact with the interlaced image.
Ideally, and it is possible with todays tech, we would have a 1080p--which is what many are recoding w/ today i.e.LOTR--onto a 1080p dvd displayed on a 1080p projector and or monitor. There would be no up-scaling or down-scaling involved. This should be avaiable by the time the PS3 is out.
