If I recall correctly, there are different rated splitters (rated in MHz) based on the color on the ends. Some are rated to handle the satellite signal. Maybe you have a splitter that can't handle the signal in line somewhere? There is a thread SOMEWHERE on this forum that talks to that. Just a thought.
