At the beginning of the movie there were a couple of interesting things that happened. First, KGO-DT flipped back and forth between DD5.1 and and non DD5.1 a couple of times. Also right at the beginning the video looked MUCH more detailed and saturated (but still 4:3) but then it switched to a lesser quality version. In fact, it looked sooo gooood that I would have been willing to risk burn-in (my set locks into full on 1080i input). After things settled down, I switched to the ATT cable version and really enjoyed the show.
best,
