LG A2 48 Inch Oled TV Remote to Control DTV Receiver #H25-100

Recently I purchased a ne LG A2 48" Oled TV.  The magic remote, model #MR22GA, during set up of the TV appeared to be paired with the Direct TV receiver, model #H25-100 (mfr date 04/10/12).  However, it will not change the channels of the Direct TV receiver.  Is there a way to resolve this situation or would we need to upgrade the receiver?

Thank you,
