Code is 463 (under Orion) for Comcast Black Remote (I work at comcast and insignia is not on the code list) Someone called in with this problem. I checked this site for hints... none of the emerson ones worked, tried the orion codes and the last one worked (463). This is not for the newer silver remote... its for the black one that came out b4 the silver one. Just wanted to add that since this site ws helpful to me.
