I have noticed flickering on ESPH HD during commercials only. I just recently started receiving the national feed of FOX HD from NY. I just watched the football game in HD and it was fine, as were the commercials. Now I am watching 24 on FOX HD, channel 88 on D* and it is flickering and there are audio sync problems as well. This seems to be a problem in 1080i, 720p, and all other resolutions. Any new word on what's being done to fix this?? I searched and couldn't find any other threads on this issue. There is a petition started over on AVS for this exact issue:
