The OK button on the remote no longer works as of this morning. The light on the front of the DVR flashes, so it's getting IR 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. Used the STB power key on remote and ended up in some sort of gray diagnostics screen. Had to pull the power to get it to reboot and that did not fix the problem.
UPDATE - I tried the mobile app and same problem - all buttons work on the mobile app except for OK, which does nothing on the DVR.
