Paddy is right, a DVD Player should be region free. But this is not the only obstacle when buying NTSC DVDs. The DVD players can usually play all formats - NTSC, PAL and SECAM, but not all TV-Sets can display this. E.g. here in Germany PAL is the standard and there are still a lot of TV Sets for sale which can handle PAL and SECAM, but not NTSC. You need to check the manual of your TV set to see what standards it can display. Most Sony TV sets are usually multi-system capable, as they are sold around the globe.
