I have an elliptical dish that has 4 lnb's--61,91,110,119 Right now I have 2 lnb's connected 91 & 110.. 110 obviously for DN, is capturing signal and working fine 91 for BEV is also capturing signal but not showing image on screen .I have made sure that the correct port is selected. Can anyone tell me what I need to do in order for bev to play. also when I first connected this last week, bev played for 2 seconds then went black.-no audio or video, but signal and quality levels were pretty decent. Please offer any suggestions if possible Thanks
