If anybody has a duo node, a single HOPPER and a vip 211 receiver try plugging the vip into te second host port; it should work based on previous posts. Then disconnect one of the 3 inputs from the lnb to the duo node. It should still work as each coax of the lnb can support 2 sat signals x 2 coax = 4 sats worth of tuner.r
That is exactly what I was proposing above. This may or may not work depending upon what the duo node does with only 2 LNB inputs connected.
