The Tri-Wizard Cup may not be in the cards for Blu-Ray owners today. The special collector’s set which came out this week containing the first five Harry Potter films on Blu-Ray accidentally shipped with an HD-DVD version of Harry Potter and the Goblet of Fire. Warner is aware of the problem and has begun working on a way to replace the discs for owners of these sets. Don’t worry. Harry has a way of working himself out of problems like this.
