Hello everybody, I have an old TV that requires a RF modulator to use the DVD player. My problem is how to hook up the modulator. There is no make so I can't download a manual. There is a cable in and to TV connection.There is a audio in and a audio out and a video connection. I also have a cable box and a A/V receiver. I hope this is'nt confusioning, I certainly am. Thanks as I'm about to junk the TV. Any help would be great.
