Some advice would be appreciated. I have several DVD's which I cant play on my DVD player~it gives me some error message about PAL not'reading' . I understand that this may be something to do with'regions',and the fact that my player cant'read'the DVD . As I would like to get DVD's from the USA, for example, I would like to know if there are any DVD players(Not Blu ray!)that play all DVD's.. I know the reviews mention PAL scan,NTS and such like,but these terms mean little to me...grateful for help
