Does anyone experience this problem? If I press the "Select" button, it takes about 5 seconds for a response. Or, if I press the "Guide" button, it also takes about 5 seconds to react. For that matter, any button I press. The weird thing is that is comes and goes! If I reboot, it helps for a day or so, then it starts again. Very frustrating. Any idea's out there???? By the way, I have the newest DVR. (Sept 09) I think it is the HR24??
