I just purchased an RCA DVD Recorder model DRC8030N. My setup is the cable from the wall to a splitter. It then splits to a cable box and tv in one room and also to the dvd recorder in the other room. I have the cable going to the receiver and then a cable from the recorded to my tv. Im getting all the channels on my tv yet when I do a channel search through the recorded its only finding 4 channels. How do I get all the channels recognized through my recorded so I can record shows from any channel?? Someone please help before I throw the machine out the window
