Be patient......When working with IR systems I have found the biggest problem is crossed wires or using some of the generic emitters that some equipment comes with. (ex. vcrs, sat.) Find the manufacturer of your choice and stick with their product. I prefer using Xantech products. They started the IR revolution. Thon is exactly right... hard wire when possible. If you get in a bind call tech support... they can walk you thru your system and generally find the problem.
