I received a free DVR upgrade (HR22) to replace the H23 receiver in my bedroom. I have a HR20 in my living room. The HR20 and the H23 are currently networked with DECA. The H23 that I'm replacing has one cable input and one DECA attached. Directv did not send me everything so I can hook up both tuners. I have a few questions: I think I need a splitter and one more DECA? Does the splitter go before the two DECAs and then the DECAs outputs into the DVR tuner inputs? Then one DECA ethernet output goes to the DVR ethernet input?
