I’ve been working on this with the Ceton people since I started the topic. I’m still not sure what’s going on but I’ve discovered a couple of things. At least part of the problem is rebooting the computer. For some reason the USB tuner NEVER comes up in the Ceton diagnostic thing. It shows up in device manager and I can even browse to the device’s web interface but it’s like Media Center can’t see it. I’ve had this happen independent of a reboot but it happens with EVERY reboot. I have to pull power on the device and plug it back in and it seems fine (knock on wood). I’m still not entirely sure my initial problem wasn’t a cable or power issue but the reboot thing seems to drive the USB device nuts for some reason.
