I am having this same problem! Did you ever find a fix?

Ya I did. You have to choose to manually set it up.

Could you be a little more specific? I did try setting it up mannually. I selected cable, answered yes to set top box, and then get the error that the IR hardware is not detected but the remote does work with MCE. It's even a windows remote. Although, I do have Vista, maybe that's the problem?

You got Vista Media Center to read it? I got vista and after installig the drivers vista keep saying no turner hardware installed when I went to set it up. Are there Vista drivers out for it? I have analog cable and my new tv tuner I got for vista is only digital so it would be great if I can get it to work with vista.

 

From what I remember when setting it up you select to manaully set up. Choose your signal(cable, antenna, etc) then cable providers(if using cable) show up select one then your done. It shouldnt say anything about a ir device, it didnt for me.

Well I didn't have any problem with Vista recognizing it. I do know there are drivers on Dell's website to download for it though. I did go to set it up manually and got as far as you say but at the very end it gives me the error that it can't find IR hardware. My remote is RF, not IR so I'm not quite sure what to do. What bothers me is that it did work when I first got it and now it's not. I've even done a system restore and everything. I have the Dell tv tuner that's made by lumanate, it's the single tv tuner. I have read a lot of forums where other people have your same problem, maybe you can read those?
