Actually with only minor exceptions, OTA should always be top of the list as far a PQ of network television....


Something is terribly wrong somewhere if OTA-HD isn't the best PQ, period. Either some adjustment is out of whack or there's cockpit error.

MPEG-4 HD on some channels via D* can come very close, but OTA-HD is king of the hill, and there are technical reasons for this to be the case.

i agree. you guys are correct. ota to first of the line. then Directv :D

DTV picture was worlds ahead of my crappy comcast picture. There was certainly some certain channels in my market anyway that I noticed a BIG difference. Discovery, Universal HD and USA were awful on comcast.

You are right about that. When I had friends over last saturday for a get-together, we were watching the 2nd half of the Yankees-Red Sox game on FOX. One of my friends has Comcast while the rest have Cablevision. Since I have D*, one of my friends says that the HD on the D* look a lot better compared to the HD on Comcast in his house. As for the rest of my friends, they also noticed some difference between DirecTV and Cablevision HD PQ.

On the other hand, a TV provider like DirecTV or Comcast (or Verizon or AT&T, etc.) could be pulling in a feed over fiber before that final stage of compression, and so could be delivering a higher-quality feed than what goes out OTA. True, most OTA stations are actually picked up OTA, recompressed using MPEG4 (with very little additional loss in most cases), and sent out, but some feeds are fiber and are very high quality.

Even the fiber feeds to the providers are only carrying that station's MPEG2 stream.

A station isn't going to spent the initial capital, nor pay more monthly for additional bandwidth, to provide a different feed to other providers.

Yes, local stations could...but they don't...it's either ATSC OTA pickup...or the same MPEG2 via fiber.

Better PQ supplied by locals to cable and sat is an interesting myth. What TV station would market, "Don't watch OTA when cable or sat has our best picture ever!"
