Another thing to consider: virus software. I've had a McAfee anti-virus that came with my Dell. Since I installed the Ceton card, I had to run the TV Signal setup every time I rebooted the computer in order for Windows Media Center to find the CableCARD. Well, my free subscription expired on the first of the year and I uninstalled the McAfee software and replaced it with Avast. Since then, no problems in Windows Media Center with the CableCARD.
