I am the same way. We only have 2 remotes, but I don't even know how to get the channel guide on. DH is always talking into the remote and then gets mad when the thing doesn't get his command correctly. He uses voice for everything. I just think it's dumb.
I do know how to get my DVD player to play a DVD, which I mostly use for yoga or other workout stuff. That involves 2 remotes, but I've been doing it a long time.
One time, many years ago, when my kids were away at camp and DH was on a business trip, I rented a movie (a tape). I couldn't get the movie to play, so I returned it within an hour. How pathetic is that?
