Hi there,
i just get the TV today and i have a few questions.
i have a bluetooth speaker connect to the tv but every time i turn on the TV it ask me if i want to pair it.. can i make automatic? its a bit boring have to check yes allways.
there is any aplication for i see mkv movies, the one that comes its a bit weak.. i look on the store but cant find anyting
how can i add shortcuts to the remote ( when press the button 123)
Anyone knows where i can find the calibration settings?

@Halqet: Are you switching off your Bluetooth speaker when you power off the TV (at night, for instance)? If so, the user manual states, "When you turn on a paired Bluetooth audio device, the TV detects it automatically, and then displays a pop-up window. Use this pop-up window to activate/deactivate the Bluetooth audio device." With this in mind, it does appear that you will have to manually enable the speaker after you initially switch on the TV. 

Please be aware that when using the 123 button to access the Shortcuts menu, it is only possible to add a shortcut for the following options: Sources, Channels, eManual, Settings, TTX and broadcast type.
