I just bought and setup a new Roamio Pro, moving my XL4 to the bedroom. After connecting the XL4, I found that the remote will not cause anything to happen - in other words, when I press buttons on the remote, the amber circle appears on the XL4, showing that a signal is being received, but no action is taken. I am stuck on the "My Shows" spot on the TiVo Central screen. I am pretty sure that the problem lies with the XL4, not the remote, because I get the same response from my Harmony One remote that I had been using to control the XL 4.
Please help! I cannot even get to the CableCard Pairing screen to call Comcast!
