As of right now I have 2 HR24 DVR's and a H25 receiver so I assume I have a SWiM 8 installed. We're just finishing up building a bonus room that I want another DVR for. Since I just had equipment added in January I don't qualify for any discounts from D* so to do so I'll have to pay full for whatever I get. Now if I get another HR24 I should be good to go since I'll be at 7 on the SWiM but I may spring and get a HR34 which will take it to 10 so I'll be over what my present SWiM is capable of. Other than getting a SWiM 16 is there anything else I need? I figure if I could order from D* they'd know what I need but since I can't order a HR34 from their site I'll have to go elsewhere.
