HD DVD and Bluray are both high definition disc formats but they were not only competitive formats but incompatible formats as well. While the battle for the HD market was in progress a handful of players were sold that would support both formats. These players were expensive and very few were ever sold.

A DVD player cannot play a BluRay disc. A BluRay player can play both BluRay discs and DVDs.
