I've heard on this forum that OTA HD PQ is superior because D* compresses their HD programming to save bandwidth on the satellite does D* do this with SD programming, too? If not, what would cause the noticeable difference in PQ between the OTA SD picture and the satellite SD MPEG-2 picture? I'm making the comparison by toggling between a local station (via satellite) and same station via OTA with output set at 480i and the OTA picture (even at 480i) is noticeably sharper. Is this a fair comparison? Some of the satellite stations are really poor. I'm a transplanted Chicagoan, and Cubs broadcasts on WGN are really awful (in addition to the Cub's play itself). Any explanations and/or suggestions? My satellite signal readings are in the 90's, and so I don't think signal strength is a problem. The OTA antenna is diplexed into the satellite feed going to the HR10-250. Any info/suggestions are appreciated.
