Greetings! I have a DPS 322 operating 2 TV's. Recently TV2 has started changing channels on it's own, setting timers, scowling through the channel guide etc. I shut off and disconnected a home theater located near by thinking it was affecting this.....nothing. I've switched to another IR remote.... no change. It's actually kinda of entertaining when theirs nothing interesting on, but I'd like to fix this. Any ideas?
