I have a Dishplayer and have the exact same problem. Never figured out a way to fix it. Interestingly enough 1 out of maybe 10 times it actually works correctly. I can't imagine what would cause this. I always point it directly at the Dishplayer's IR port. Maybe its the state that the remote is in when I press the shutdown macro. Or I wonder if it has anything to do with where in the macro the learned function is placed. I have it try to turn off the Dishplayer before anything else.
