My brother is trying to hook up pip to his new rptv. He has a hitachi not sure what model. If important I can get it. He has digital cable box, VCR,DVD player. What is the correct way to run cables/wires to get this to work properly? What setting does the vcr have to be on? Where does the split need to happen? I told his this forum is the best I'll have a answer for him tomorrow.
