I tried to Hook my Sony DVD recorder[Mod.#RDR-GXD455] to my Dish reciever [Mod.#vip222k]. I cannot get a signal to my DVD recorder. But the signal passes thru the Recorder,to the T.V. I even tried an RF Modulator. I tried all the inputs on the T.V. remote. I would like to do some timer recording.Can anyone suggest something I missed. That would be most appreciated. Thank You
