Instead of running the EIV, can you pull up the signal strength of each DSWM channel? If so, what does it show for 2 and 10 (and the rest)? Do you have a 3D2RBLNB to connect and run the LNB EIV on? Also, when you check the system, how does it know if you are at the LNB or the receiver? You tell it? What difference would it make where you are? I guess I don't understand what it's checking in this part. But regardless, very interesting about the difference in reported tuners based on location; it's definitely starting to look like a system (receiver) imposed limit.
