I am confused by a choice being offered by the installer and would appreciate advice. I had originally intended to install two dtivos and have already received them as well as a Directv "Multi-satellite dish antenna with Integrated Triple and Built-in Multiswitch". I more or less understood that you need 4 connectors for two tivos and that this satellite has it. I have now decided to add one basic receiver so I guess I don't have enough connections and I am being offered a choice of a free "3x4" switch or a 5x8 that I have to pay for. I do not understand the explanation of the difference but somehow adding the 3x4 seems like its downgrading the satellite because most of the outlets would be limited to the "101 main satellite". Is that bad so that I should pay for the 5 x8 switch even though I don't seem to need it for my present needs? To the extent that I think this information is relevant, I do not have hd and if I got it in the future would not likely get more than one, I do not need Spanish channels and I live in a Chicago suburb.
