I have an unsupported deca-less setup with the following equipment: SWM16 switch 2 8-way splitters (green label) 2 HR-24s 4 HR-20-100s/700s I have 6 tuners on each of the splitters and a PI on one of the splitters. I believe I need 4 DECAs for each of the HR-20s and 4 BSFs too? Do I also need a DECA PI? Where does this go? Finally, do I need something else to bridge the system to my network switch? I have several in the house so I can flexibility in where I connect the DECA setup to my home network. FWIW, I am thinking of making the change because my setup is not always reliable. Sometimes I cannot see one DVR's playlist from another DVR and have to reboot them to get it to work. Maybe the change won't resolve this. Who knows?
