According to the D* rep I spoke with on the phone I need an HD DVR (got that) and at least one other HD receiver. Is that correct? I thought I only needed one HD DVR and that my R22's were DECA compatible? I've already got SWM hooked up. Few more questions.... 1. Is there an online diagram that shows how the DECA system is hooked up? 2. Do I need to run an ethernet line from my router for MRV to work, OR is the ethernet only for On Demand? 3. I would like to install this myself......do I just need the DECA box, DECA power supply, and a band stop filter for each DECA box? 4. DECA power supply.....one power supply for each DECA box, or does that power supply send juice to all the DECA boxes? Sorry for all the questions and I hope this hasn't been asked before.
