I have been having this problem as well. Every now and then I will lose the 110 and 119 satelites. The problem is that I have been extremely busy at work and every time I try to troubleshoot the problem the 110 and 119 sats are working fine. I haven't had time to check the other receivers when this happens since they are all SD I wouldn't notice when watching them. Next time it happens I am going to check for signals on the other receivers. I hope this is an easy fix because it is really annoying to lose the HD pack every so often for a few hours.
