I have had my BBC installed after my multiswitch and before the first diplexor for several months now. This has been great, it has worked flawlessly and I have recieved my local HD channles OTA adn everything else fine, until now. It seems as though when the switch some channles the new satellite I lost them? I now can't get EPSN and ESPN2 on 206/207, only get them on 72/73. I also don't seem to be able to pick up Fox sports HD and a few others? Would this be due to my diplexing setup? Something else?
