Two major theatrical releases went head to head on DVD, and they each won... in different categories.

Harry Potter and the Order of the Phoenix ended up as the biggest seller, while The Bourne Ultimatum was the top rental, in the week ending December 16. The split-decision wasn't all that surprising, since the films combined for a total theatrical haul of $519 million.

Harry Potter and the Order of the Phoenix outsold both The Bourne Ultimatum other notable newbie High School Musical 2 in third place. Last week's winner, Pirates of the Caribbean: At World's End took fourth place in sales.

On the rental side, The Bourne Ultimatum took home an estimated rental revenue of $15.4 million while Harry Potter and the Order of the Phoenix came in second with an estimated rental tally of $12.3 million.

Both discs performed nicely in the high-def markets as well. The Bourne Ultimatum outsold Harry Potter and the Order of the Phoenix on HD DVD and Potter took second on the Blu-Ray charts as well, with last week's Blu-Ray winner, Pirates of the Caribbean: At World's End the top seller for the second week in a row.
