Teaching AppleTV (2nd Gen.) to Learn a Directv Remote

So in playing around with my new AppleTV, I found the feature of teaching it to learn a new third party remote.  I figured I would give it a try and surprisingly it didn't work the first time around.  I kept getting an error saying the button was already used.  In searching around the net I found and compiled these instructions for my DirecTV remote.  While they may not work with your particular remote you should get the general idea.

How to program the DirecTV remote to your TV

1. The control code for your Apple TV is 20533.
2. Make sure your TV and Apple TV is turned on.
3. Slide the mode switch at top of remote to "AV1".
4. Press and hold the MUTE button. This is located above the number 1 button.
5. While still holding down MUTE, press and hold the SELECT button until the green light at the top of the remote flashes twice.
6. Enter the code for Apple TV - 20533. The green light on remote should flash twice.
7. Aim remote at TV and press PWR button once. The TV should power off.
8. Now using the Apple Remote go to Settings>General>Remote>Learn Remotes
9. Follow the step by step directions
10. Select Start (using the Apple Remote included with Apple TV).
11. Apple TV will display icons that represent the six buttons on the Apple Remote with the "Up" button highlighted first.
12. Using your DirecTV remote, press and hold the button you would like to use to control the "up" function until the blue progress bar is full as shown below.
    
13. Apple TV will then select the next button function.
14. After you have programmed all six button functions, you can now use your DirecTV  remote to control Apple TV. You can optionally setup specific playback buttons for Fast-forward, Rewind, Next chapter, and more.
15. Your DirecTV remote is now programmed.
