The OK button on the remote no longer works as of this evening. The light on the front of the DVR flashes, so it's getting signal from the remote just fine. All other buttons seem to work fine, but it's ignoring the OK button. Tried the upstairs remote and same thing (and the downstairs remote works fine on the upstairs STB). As it stands now we can't select a channel to watch out of the guide, nor can we select something off of DVR to watch.
