Most DVD players are capable of being made multi-region with a hack. Just type into google - dvd manufacturer, model number, and the words multi-region hack - (eg. philips dvp3020 multi-region hack) and you should be directed to the information. In order to watch both PAL and NTSC discs you must have a compatible TV. If you haven’t the picture may appear in black and white or not be viewable at all, but most UK tvs these days seem to play NTSC discs ok, so I presume US tvs will play PAL.
