I live in the USA. Can I order a video from Amazon UK?
Different countries have different standards for videos and television
signals. TV broadcasts and videos/DVDs for sale in the USA, Canada and Japan
are produced according to a standard called NTSC; most European countries
follow a different standard called PAL. We won't go into technical details
here: suffice to say that a PAL-format video requires a PAL-compatible player
and television set, and the same applies to NTSC. If you live in the USA you
cannot play videos manufactured for sale in the UK and vice-versa. The
only exception is if you own a high-end multi-standard VCR player and TV (i.e. a
set that is designed to be compatible with both video standards).
The same is true for DVDs, with an additional limitation: DVDs are
region-encoded, i.e. have a special code to ensure they can be played only
on players sold in the same country or geographical region.
For example, even though Japan and the USA use the same video standard
(NTSC), a DVD released in Japan (region 2) will not play on a DVD player
sold in the USA (region 1). See this guide for more information about DVD regions and video standards
