As far as I'm aware, Region 2 is for Japan, Europe (not all of it, I believe), South Africa and the Middle East and, as you pointed out, NTSC is the television format used in the US (as opposed to PAL in the UK and SECAM in some areas of Europe).
I have a multi-region dvd player hooked up to a multiple-system TV that I use to watch, mostly, British comedy series that haven't been (or won't be) released in NTSC. (League of Gentlemen, series 2, 3 and Christmas special, Little Britain, Ali G etc.)
However, I'll try it on my normal, Region 1, dvd player to see if it will work for US viewers. I don't have any way to test if it will be viewable in the UK though...
Of course, if you have multiple dvd-player programs on your computer then you can always set each one to a different region and use that to watch it - which is what I used to do before I had my multi-region dvd player.
And if you're feeling adventurous, you can fiddle with your dvd player. Go here to read of one individual's endeavours in this regard:
