I have a Magnavox TV with a single input in the back. How do I hook up my RCA DVD and Satellite dish to utilize both? I only have the manual for the TV, and the book for the satellite only covers use of the remote. I also have a RF modulator if needed.

It sounds like you have a TV with only a single co-ax input?

Without the component inputs, Right and Left audio and video, you will not be able to hook everything up without some type of adapter that will allow you to use a co-ax hook up to the TV.

If you are near a Radio Shack, if you explain what it is you are trying to do, they have answers, and the adapters for your problem.

What you would need to do is connect the satellite receiver to the vcr with coax then from the vcr to the rf modulator with coax then to the TV with coax. For the dvd player you would want to take the rca jacks(yellow, red, white cables) and connect them to the rf modulator. Everything should be on channel 3/4 on the TV
