I have a genie that I set to 720p for a variety of complicated reasons. I am finding that some channels have a stutter on the image. This problem has existed for a while on Comcast Chicago during baseball games (I don't remember seeing it during hockey games and it seemed to happen more often with Cubs games than White Sox games which is bizarre). The problem occurs when I download on demand soccer games from Univision Deportes but never when I watch live or DVR games from Univision Deportes. And now I am seeing the same problem on TBS East while watching the MLB Wild Card game but not on TBS West. The problem never happens during TV dramas/comedies/movies and only during sports. I really don't know how to describe the problem other than as a stutter. The closest thing I have seen is when someone converted a PAL DVD to NTSC or vice versa and the image isn't smooth: every 15-20 seconds there is a stutter. I have tried changing the box to 1080 but there was no change. Does anyone have any advice about ways to solve this problem? It's bizarre because of the lack of repetition across channels or even within a specific channel.
