Hello, I am in the process of building a new home. I have been with DirecTV for 10+ years (have always used the DirecTV DVR's) and am going to be switching to Comcast when we move in. I have heard that the Comcast DVR's are junk, so i'm going to get 2 TiVo DVR's for our two TV's. Here are a couple questions I have: 1- What exactly do I need to connect both TiVo boxes so I can see and view the recorded shows on each box. I will have both units connected to my router, is that good enough? 2- Can each unit see the other unit, or can you only watch recorded shows on another TV from one specified unit? My DirecTV DVR's could all see each other and you could watch any recorded show on any unit. I'm hoping TiVo works the same way. 3- Only 1 coax is required even though you can have up to 4 tuners (with the high end model), correct?
