You didn't give your emerson remote model number but you may have to do a "code search" with it until you find the right code

Direct (and Dish) may not have codes available for all brands and models; I know that from personal experience.
You need to got to Direct TV's website to obtain a current list of codes. Even if they have some for Emerson, they may be quite limited in their usefulness.  

I went to the Little Leaps website and went into customer support and viewed a link that provided additional codes. I have the Emerson dvd player with video cassette recorder EWD2203 and the code 027 which was listed in the additional codes at Little Leaps website worked for me.
Here is that list of additional codes from the Little Leaps website:
018,030,035,005,150,151,043,058,011,147,148,016,004,002,144,007,009,146,013,020,027,133,042,129, and 149.
These codes were listed to try with any players.
Good Luck.
