Recently purchased a 2008 Big Horn and would like to get a DVR to work. I'm currently using old receiver from 2009 that is working fine. I was planning to move it to the bedroom and go with the DVR in the L/R. Everyone I've talked to says I need 2 lines coming inside to get the DVR to work. Not quite sure how to accomplish. I'm using an older round dish on a tripod. I'm not sure what kind of equipment I need to get. I don't really have to have an HD setup--just want the capability to record and pause. Any help would be greatly appreciated.
