The IR function on our HR24 is downright frustrating. Sometimes it takes IR sometimes it doesn't. There is no rhyme or reason to this. Very frustrating to try and watch TV to have the remote function so poorly. I decided to get it switched over to RF to see if that would solve the problem. The problem is that the RF programming isn't taking hold on the HR24. Now I'm stuck and frustrated. I've tried the red button reset. I've tried two other remotes and they all aact the same way in IR and none will take hold with the HR24. Yes, the remotes have the FCC sticker on the back and I know for sure they do RF as I controlled an old HR22 about a year ago via RF with the remote. Any suggestions?
