here' my current setup: 2 - HR20-700 DVR 1 - Slimline dish (i don't think it's SWiM compatible, it has 4 lines coming into the multi switch) 1 - Zinwell 6x8 multiswitch DVRs are in a separate room. I just want to be able to watch recorded shows from either DVRs in either room. I don't want internet connection. from wha I've read all I would need is a SWM splitter (MSPLIT8R0-01 or MSPLIT4R0-01) and a SWM-LNB Power inserter 21V DTV and two DECAs (one going to each receiver). one line from the Zinwell switch will go into the SWM splitter. from there each line will go to the DECA and into the HR20-700. if I don't need internet do i need the LAN cable? the question is, once I have this configure what else do I need to do? Do I need to call DTV to activate MRV? or will this work as soon as I configure everything and reboot the receivers? thanks.
