Advertisements I currently have 3 DirecTivos (2 Series 1 DSR6000 and 1 newer R10) running through a 2x8 multiswitch that gets fed from one 18" round dish. If I want to add a DirecTV HD box (DVR or otherwise) into this setup what do I need? I assume I call DirecTV and say I want to upgrade to the HD package which will require a 5 LNB dish? Is this correct? How does this wire into my current setup? Does anyone have a link to a wiring diagram? Thanks!
