I really need some help. I have my 625 dvr in single mode and my setup is from wall to splitter, from splitter to satellite one and two. Then I have s-video out from satellite into s-vhs player, s-video out from s-vhs player to back of my tv. I do not receive a picture, just a blue screen. When I substitute s-video cords for coaxial cords, I am able to do everything except record. I press the record button and nothing happens. My vcr is HR-S5912U.
