you enter the wrong menu, you should enter on ez-adjust menu, not instart.
the correct button is the red-cicled one, the default password to enter is 0413.
based on the code i see on your photo, you should have already dvr enabled, you can enable dolby atmos using this code "541842440"
if long pressing the red button say that your tv does not support recording, you must change country to other one (like germany)
