I am having trouble getting the player to switch between player and tuner mode using a long press of my source buttons

[ir_translate]
00AD520A=0020DF13 ; volume up
00AD520B=0020DF17 ; volume down
00AD520C=00000008 ; Knob press/ATT
00AD5212=0020DF14 ; info/Band
00AD521A.LM=0020DF07 ; tuner/ long player source
00AD521A.LT=0020DF03 ; player/ long tuner source
00AD512A=0020DF14
00AD5240=0020DF0C ; up/cancel
00AD5242=0020DF10 ; left/left
00AD5243=0020DF11 ; right/right
00AD5241=0020DF12 ; down/menu
00AF5067=0020DF0D ; func/shuffle
00AD520D=0020DF02 ; audio/source


Anybody got a clue as to my goof up
