DVDs and videotapes of Harry Potter and the Sorcerer's Stone were flying out of stores faster than a Nimbus 2000 yesterday.

Diehard Potter fans showed up at the Virgin Megastore in Times Square at midnight to get their hands on the first video copies of last year's top-grossing movie. 

"It's been selling as fast as I can fill the racks," said salesman Maximo Lara. "No one's buying anything else." 

Warner Bros. wouldn't say how many videos were shipped, but the trade publication Video Business estimated that Sorcerer's Stone would sell 18 to 20 million copies on VHS and DVD in the United States. 

In Britain, where Harry Potter videos were released May 11, 1.25 million copies were sold in the first day — topping the record held by "Titanic." 

The VHS and two-disc DVD set each contain a handful of deleted scenes. The DVD also has interactive games, a tour of Hogwarts, interviews with director Chris Columbus and a sneak peek at Harry Potter and the Chamber of Secrets, due in theaters this November.
