OK, dudes, I've been researching for a couple weeks now and I think I have it figured out. What I have: Slimline (the non-swm kind) SWM-8 multiwitch 1x4 splitter feeding 4 HR21s What I'm adding: 1 HR24 4 DECA modules. My first question is this: Should I upgrade my 1x4 splitter to a 1x8 to accommodate the fifth HD DVR or should I just use the second SWM output on the SWM-8? I know the power inserter powers the entire SWM-8, but will MRV work with the lone HD DVR that's connected directly to the SWM-8? And the other thing I have yet to find a solid answer on is if an internet connection is REQUIRED for Whole Home DVR. One of the FAQs on this board says no, but I wanna be sure. I don't care about on-demand or remote scheduling. I just wanna utilize MRV. Also, I have one non-HD receiver connected to the legacy port on the SWM-8. I can just leave that guy as is right? If you guys need me to make a schematic in MS Paint, I can do that. Thanks in advance. Oh yeah, one more question. Can I have Directv send me the DECA modules without the installer? I wanna do this myself and wouldn't mind saving $50 by not having an installer come to my house.
