The reason I was leaning towards the LNB being the problem, is that it started after the new dish was installed to support the 722. I still have a couple of 501 tuners in other rooms that never had this probelm, but now they do. I would assume that 501s didn't have any type of software change.cmtar said:Could be wrong but i would a software problem because if all other channels are find then the lnb's are working fine...right?
What do each of the three LNBs support? Does one of them receive subscribed locals only?
