Advertisements I am considering the addition of a 3rd DVR with Tivo and wonder if I can do it myself I currently use an HR 10 HD DVR in one room and Std Def DVR in another room. The 3rd DVR I would like to hook up in another room is a Std Def DVR. The Question is can I do it myself and how do I do it? I went up on roof and determined that there are 4 cables coming from my triple lnb dish into the house. 2 go to the HD DVR and the other two go to the Std Def DVR. Do I need to run 2 more cables (that would make 6 total) from the dish or is there some other way you go about creating two cables that need to be run for 3rd DVR I want to install? Based on answer to the question will determine if I will need to pay a Directv installer or go about this myself. Thanks for any guidance/clarification.
