Is anyone else experiencing signal problems with FOX and NBC HD feeds in the St. Louis area? I had the service installed in July and at that time the installer said Dish was having problems with the FOX and NBC HD feeds. However, I had absolutely no issues for the first couple of months. Lately, I haven't been able to get either channel to tune in at all. All of my other HD channels work flawlessly, so I'm guessing it's a satellite feed issue and not an equipment issue.
