British DVDs in the US?

[joanne0012]

I want to buy a copy of the forthcoming HPPS video.  I know that British 
videotapes will not work in US VCRs.  Are there any techies out there who know 
whether British DVDs will work in an American DVD player?

This is a gift for a dear niece, who is the only other adult HP fan that I know 
personally.  She is such a purist, she bought the British HP series to read to her 
young kids. Since I recently spent a week as her guest, I thought this would be 
the perfect thank-you gift.  (She has already pre-ordered HPSS.)  Help!
