I am trying to get my MX-450 to control my projector screen which has an IR remote / controller. I have created a new device called screen and tried "teaching" the up, down and stop commands to the remote. It says "Good" and saves the command but when I point it at the screen controller it doesn't work. Any ideas?

I tried programming to soft buttons and even to the ON/OFF buttons but no luck. I even tried making a macro which repeated the command a bunch of times.

I will eventually be using a MRF-350 with an IR flasher pointed at the screen controller so I could try adjusting the IR emmiter strength then but I doubt that will work if pointing the "taught" remote right at the eye doesn't. Thanks for any ideas.
