I have DN working and running DVR 522 and 322. I left 322 to continue working and turned 522 OFF. Connected Pan2700A with new bin scanned and got almost everything except most PPV and some movie cnannels missing from EPG screen. Some channels I see but "no signal" sign. I did everything with setup and noticed that sometimes signal on bird 7 showing quality 99% and the bar is not moving but on 8 two green bars 80-90% both moving and vicer versar. I did some research and found out that my problem is LNBF. I do not know what kind LNBF I have. I have two cables coming from Dish 500 both separately going to each reciever. Can I fix this problem without changing LNB??? Thank's
