I've been having the same problem as well, except that I have two tuners and both are not found. I also dont think it's a hardware problem. It has to do with some sort of update. I've done system restore a few times and it works properly for a while until I start updates. I'm tired of doing system restore so I've started just restoring it to a certain date. Eventually, after doing this a few times, I finally got the tuners to work again. The Media Center is still not working properly b/c it suddenly says it's stopped working and gives me an error. I wish I could figure out which update caused these problem.

I'm interested in how you solve your problem. Please keep us updated! Thanks!
