Advertisements i have seen some have had an unresponsive remote problem upon upgrading the software. i haven't upgraded my software nor made a call in over 1000 days. everything had worked fine until the last week. i came home one day to a black screen and had to remove power and reboot. i've had to do this one two occasions now. the past few days the remote will barely respond sometimes i have to hit a button 10 or more times to get response no matter how close to the unit i am. even holding it 10 inches away doesn't omit a response. i still haven't missed any recordings during this period though. neither my harmony remote nor the original tivo peanut remote will respond. any ideas on what the problem could be? thanks.
