I've searched and can't find define answers to my most basic of questions... I'm going to keep my cable (Comcast) for internet access and VOIP (Vonage). If my wife can find a acceptable place for the dish and we don't have to have my house torn up, I want to switch. My house has all underground utilities. Coax cable is run from each room to a box outside my house. 1) If I want 3 (maybe 4) HD DVR's, can the dish be pole mounted and be directly connected to the 3 (4) runs to each of the rooms at the same box on the side of my house? 2) Do you need a phone jack next to each receiver? No location has a phone jack anywhere near and only one location has internet... I'm not even sure if the phone jacks are terminated (they have never been used - We use one wireless phone base connected to the VOIP for the whole house.) 3) The possible 4th location currently shares a homerun coax cable via a splitter. Can two receivers use just one cable? 4) On the Comcast DVR you can record two live HD programs and watch a third from a recording. Will a Dish or Direct DVR do the same? 5) Anything else I need to know?
