I have upgraded my DirecTV system at home and now want to modulate one of my receivers to a channel other than 3 or 4. I am interested in modulating one of my receivers to channel 26. I found a Ce Labs 1001st RF Modulator. Does this take a sterio input (red and white connections) as well as a yellow video connection? In this case, I am interested in a simple modulated channel for standard TVs. Has anyone done this with high definition signals so the modulator can pass a high definition channel plus 5.1 sound? Any ideas for a modulator for this option?
