Every time I buy a DVD online I have to check which region it can be played in. This would be a lot quicker if I could remember which region is which. Now most sensibly I would have attempted to remember that all I really care about is the European region 2 (of course the US had to be region 1). Unfortunately every time I check the map I attempt to learn all the regions (under the assumption that this greater understanding will lead me never to forget). Instead this leads me to be entirely confused (why are Egypt and south Africa not in the african region, for example??) and causes me to forget the simple important fact that 99% of the people I buy for need region 2.
As an alternative solution my family could always check that they've got the right region before they add a DVD to their amazon wish lists. Do you do this already?? I know I've got it wrong in the past.
