Like many, I found that code 20199 gave me most of the Samsung bluray remote's functions, but the frequently needed "Ok" button wasn't one of them. After some online searching, I found that if one programs the remote for the Samsung bluray player using the 20199 code as suggested (Note: there are several Samsung codes, the one I listed is the most common one, and the one that worked for me), THEN PERMORMS THIS ADDITIONAL STEP, functionality to the "Ok" button is restored. (Prior to performing this second step, the Xfinity remote's "Aux" button would default over to the "Cable" button, whenever Aux's "Ok" was pressed. The following step removes that mapping and restores the "Aux" button to the bluray player.
Follow these keymove instructions to restore the bluray player's "Ok" button functionality. 1) Tap AUX 2) Press Setup until 2 blinks 3) Enter 994 (2 blinks) 4) Tap Setup 5) Enter 00211 6) Tap OK/Select The remote should blink twice
