We have sat tv and a dvd recorder and I use the tuner in the dvd recorder to get antenna local tv. The way ours works is we run the sat into the dvd recorder and and the cables out the back of the recorder to the tv and watch the sat on channel 3, on the local antenna channel we have to watch on Video 1. This sounds simple but I wanted to pull my hair out until I got it to work. You may have to hire the Geek squad from Best Buy to help you if you cant make it work. I run the cables from my Video recorder (VHS) and plug the cables into the front of the dvr to copy VHS to DVD also if I record something from the satellite I have to go from digital to reg tv and use channel 3 to record from the satellite. It can into a real pain sometimes if you dont do it pretty often. Jeff
