There is no such thing as "all regions".
There is normally a way to switch between regions, although there are normally limits to the number of times you can switch.
Allegedly you can get a DVD player "chipped", but that sort of behaviour is not fit for discussion on PPRune. Your local highstreet dodgy may be able to advise further should you wish to persue that line of action.
