I've seen discussions on connecting the newer digital recievers as a slave to older analog receivers but can you connect the older receivers to use as a slave? I've got 2 older GI receivers that do digicypher 2 and powervu de-encryption. My Kbox and Nfusion HD are connected to 2 different dishs, 6' WSI Polar (DMX-741 C/KU) and a 39" (QPH-031). The 6' is run through a V-box so I don't need the analog to run the dish, but I would like to use the de-encryption capabilities. Is it possible?
