I just had DirecTV installed a couple weeks ago, and would like to have two additional receivers installed. DirecTV is going to charge me around $200 for each additional receiver, so I found two used ones that can be activated (not on existing account and not previously leased). My question is this: Since they are used receivers, I will be responsible for wiring everything up. I'm rather clueless on how it all works, but my brother in law does similar type installs for his business and says he can get everything wired/set up for me. Right now, I have three receivers (HD DVR, HD, and SD), and I believe I have a SWM install. I'd like to add the two new receivers, both being SD DVRs. Just wanted to make sure that DirecTV would be okay with the BIL doing any additional wiring necessary? I'm also not sure if the SWM can handle that many inputs (3 DVRs and 2 "non DVR" receivers)? If a different setup is required (multiswitch?) would DTV care if he changed this?? Any advice would be appreciated. Thanks.
