I just bought my second HDTV and had directv come out to upgrade my regular DVR to an HD DVR (I already have one installed upstairs on an HDTV). The question is, the installer said he couldn't do the job without installing a second line for the new receiver. I don't get it because I already have one HD DVR receiver for another tv (6 mos. ago) and the installer didn't have to put in a second line for it I am in a finished townhouse and the cables downstairs are at the opposite end of the house than where the cable outlet is in the living room. He did leave the receiver with me and it was working fine, but now when I turn it on, it is continuing to acquire data or search for satellite 2 in continuous mode. Can a splitter be used? I don't care about the feature of recording and watching another channel at the same time. I am NOT tech savvy, so any information you can give me would be appreciated!
