I just got my new Dell XPS in the mail and im trying to hook up MCE with my DirectTV receiver. I have it successfully conected with a coaxial cable, but when I try to set up the TV signal it says IR Hardware not detected. "Media Center cannot detect the hardware necessary to control your set-top box. Make sure that the IR control cable and the remote sensor are connected and then select Try Again." But I know i have sensors and control cables hooked up and posistioned correctly. What am i doing wrong how do i fix this!?
