I have not been getting 119 Sat a/c trees since June. All signal strength registers zero on my HR20. But last night, I got Disc HD theater loud and clear. I was so amazed I immediately checked the meters. Lo and behold, 119 showed 0 on all transponders, and HDNET and ESPN2 were "searching for signal". Called D* tech this morning and they don't show any migration of DHDT to other sats. Anybody know anything about this?
