I have a 722 set up in single mode. Every now and again, the channel will change, or it will bring up a menu. Different every time, but usually channel changes, which is especially annoying when I'm watching something dvr'd. (speaking of dvr, is has never disrupted a recording). I use a harmony one, and no other equipment acts up, so I don't believe it's that acting up. All I can think is that it's someone else's Dish remote for a tv2 making it happen. Although I believe that would be improbable in single mode. What do you guys think? BTW, I never had this problem until my first 722 hard drive died, and I had Dish replace it with the current one.
