Everything works great except you have to point the remote directly at the receiver to change channel. Room is rectangular and if I am off to one side, I have to move the receiver to point directly at me. Is this normal? I have a Radio Shack Remote Extender system in another room and I don't even have to point it at the receiver. I can point at the TV and it changes channels. The reason I bought the X10 was I can change the frequency and not interfere with the Radio Shack controlled TV in the other room. That part works great.
