So I accepted D*'s offer for a new HD DVR (adding a 4th box) in exchange for a contract renewal. My "new" box just arrived tonight and it is a refurbed HR-21 200. I'm not happy that it is, first, a used box and, second, that it is an HR21 and not the HR24 I was promised. Two questions: First, I have 3 existing HR24s on a DECA network with CCK installed and whole home active; I don't think the HR21 has built in DECA so it would need an adapter (which wasn't provided) right? I don't want to use one of those given the fire scare noted in another thread. Is it possible to plug just the HR21 into Ethernet to allow it to access the other DVRs on the DECA cloud? Would I be able to use whole home between all 4 DVRs in this case? If not, I guess I have to refuse delivery and hope they'll exchange it or send a tech out and hope they have an hr24 on the truck. The CSR told me she would send an HR24 since I have only hr24s installed - which was reassuring given I thought they couldn't guarantee models (now it appears they can't). Second, if I could use this new box in my existing setup, what do people think about the HR21 generally? A reliable and beloved friend, or a bug ridden bag of hurt?
