I have 4 tv's in my house. I have 3 HD tvs and 1 standard tv. I told the tech that I wanted two 211's and one 222 rcvrs. He told me that I only needed two 222's and that would give me HD on my 3 tv's and SD to my standard tv. Is this correct? It doesn't sound right to me. I want the 211's because I have a couple of hard drives that I am going to plug into them to use them as DVRs. Can someone enlighten me on this please!
