Good Morning, I'm new to Sat Guys and was introduced to it by Dish Tech. My system/service has been problem prone since installation, by Dish contractors, in June. The latest problem is trying to watch the US Open on Universal HD. This station will operate properly for a short time frame (5 minutes) and then lose satelite signal. 30 seconds later the station will operate properly for another 5 minutes and then lose satelite. This cycle will repeat endlessly. If I switch to USA Network (non-HD), which is also broadcasting the US Open there is no problem. I haven't noticed this problem with other HD channels. Dish has replaced the receiver but the problem continues. This may be the straw that broke the camels back. Any suggestions before I terminate service and go back to my cable service?
