I came home last night to freaked out kids because the 922 remote had freaked out. Pressing the Dish control button causes the light to start blinking rapidly and the remote to cease functioning properly. Pressing the Aux button, mapped to my home theater box, caused it to start blinking and the volume to get turned all the way up. We took the batteries out, replaced them, repeated, and still have the same thing. Is the remote fried? I've got a couple older remotes hanging around, such as one from our old 622 box. Can I use one of those?
