ESPN HD may be my provider getting a bad signal. Directv compresses the 1080i, but they don't with 720p. It's sort of weird having smaller files for 1080i than 720p.

I think it depends more on programming. I think the studio shows are good, but the game coverages can be downright awful. I've seen some games where the picture is macroblocked to hell and back.
Here's a sample of my unaltered 720p from Directv from a game. Not so great quality IMO compared to other channels or their studio segments.
I have experienced the same thing as far as certain programming in general. A friend of mine has a plasma tv and I have DLP, but games look much better on my tv than his. Then again, there certain shows on other channels, like UHD for example that may look better on his tv. But not all shows. Thats where I was thinking it was signal strength.

I think Ice was experiencing something similar with QVC HD but now he says its cleared up.
