Found this - did not know that the MCE remote was able to learn...
Programming your MCE remote
Some Media Center remote controls enable you to teach them to turn on/off your TV and/or control the volume of your receiver. I love this feature and recently someone emailed asking how to set it up. Fortunately a co-worker had a manual because I couldn’t remember how to do this.
To program buttons on your MCE remote control.
1. Place the MCE remote control head to head (2 to 3 inches apart) with the remote control from which it is learning.
2. On the MCE remote control press and hold the DVD MENU and OK buttons at the same time until the remote control lights turn off (2 seconds). The remote is now in learning mode.
3. On the MCE remote control press and release the TV, VOL +, VOL - button, depending on which command you want it to learn. The MCE remote control lights blink once to confirm the selection.
4. On the remote control that is teaching the command, press and hold the button that you want the coressponding button on the MCE remote control. The MCE remote control lights blink twice to confrim the selection. If the remote does not learn the command, the lights blink quickly four times. To try again repeat steps 1 through 4.
5. Repeat steps 1 through 4 for the other buttons that can learn commands.
To restore:
1. Press and hold the DVD MENU button and LEFT navigation button at the same time until the MCE remote control lights turn off
2. Press the OK button. The lights will blink twice to confirm that the buttons have been reset. If not it will blink four times.
