I figure, you are noticing that the 1080i has greater chrominance and luminance bandwidth than 720p. > But, when I compare 1080i material and 720p material > from transmitted sources (OTA, DBS, Cable, etc.), the > 720p format wins everytime at any distance, independent > of the screen resolution (that is 720 or higher) and > especially if motion is involved. The interesting test would be to see whether a 25 or 30 Mb/s channel changes that result for 1080i transmission.
