This was regardless of the output resolution setting of the dish box. Even using my receiver to convert 1080i to 1080p the channels still had the same issues.
On distance shots where the players are small and there is relatively little movement compared to the overall screen area is where I see the biggest issue. But talking heads of side line reporters show this robotic or dropped frame issue too. In particular there was a graphic on half the screen, report on the other with players running in the background. When the players weren't there the face was robotic and dropped frames. Once players started moving in the background something kicked in and suddenly things were fine. It would come and go based on this background movement.
Using Digital Clean View on Auto did seem to lessen the problem ever so slightly. Auto Motion Plus on Auto rather than Custom helped slightly on some content too (football). Turning AMP off there are no issues but the blur is not tolerable for me.
Not quite sure where to go from here. I want to say it is a source issue but different channels from different boxes and only on 1080i sourced channels seems odd. At the same time, if my receiver converts to 1080p I don't see how the TV would ever know the source resolution was 1080i and still have the issue.
For "interlaced" sources, make sure you turn ON "Film Mode".
From my >> Picture Settings Guide
This setting optimizes the picture quality for 24fps film based content. However, it is only applicable for interlaced
input signals (480i, 1080i) and will be "grayed-out" for a non-interlaced (progressive) input signal.
24fps film based content needs to be converted into 30fps video for TV broadcast using 3:2 pulldown technology. The TV needs to be able to detect this 3:2 pulldown sequence (or cadence) in the incoming interlaced signal in order to correctly process it, using a process called 'inverse telecine' or 'reverse pulldown' to remove the 3:2 pulldown, and de-interlace it.
"Film Mode" engages a process called 'Cadence Detection' which detects the 'cadence' used when converting 24fps film based content into 30fps video for TV broadcast. This allows the video processor in the TV to correctly process the incoming signal so that the content can be properly displayed without interlaced artifacts or loss in picture resolution. This process effectively smooths out frame transitions, minimizing 'telecine judder'.
"Film Mode" has to be turned "ON" for 3:2 pulldown 'detection' and 'correction' to work properly. It needs to be set to "Auto 1" when viewing 1080i content ("Auto 2" when viewing 480i content).
