I want to add 3 buttons that are on my samsung tv remote to my Atlas remote. I learned how to add buttons over at this thread: [Link: remotecentral.com]

So I know how to add the buttons, but, I don't know the EFC codes for the buttons.

(So this is a bit of a cross-post, but I figured I should since that other subforum was the wrong place apparently)

The cable remote is the Atlas DVR 1055, and the Samsung tv remote is the BN59-00687A

The tv remote has buttons: "P.SIZE", "SOURCE", and Enter (the circle one in the middle with an enter icon)

If I can get those buttons onto the Atlas then I can put the tv remote away and be able to use the Atlas on its own. How can I find the 3 codes I need?

EDIT: Also, If we can't figure out the codes, can I point the samsung remote at the atlas remote and get the atlas to "learn" the buttons???
