1160 # - normal playback                       TUNER    unused      PLAY               enable                disable              disable

1164 # - end of timeshift buffer reached       TUNER    record      PLAY               enable                enable               disable

1170 # freezes the picture (to indicate timeshift), sets timeshiftMode ("activates timeshift")
