Query: HDDVD?????

Boo hoo! Boo hoo! Son was really wanting this movie for a long time. I wish Mrs. Claus better understood HD DVD. Now he has the movie, but nothing we own will play it. I read carefully before purchase and didn't see where you needed a special player to play it on. One that most people don't own. I should have googled before purchase not after. Lesson learned. Hopefully, this will help someone else before they buy.
