Bluray and HD DVD are the two trade names for high definition discs and players. Bluray is by far the better choice for the simple reason that HD DVD was withdrawn in 2009. Bluray had won the HD format war so HD DVD quietly left the stores. There are a number of HD DVD discs around as well as the players. As the two systems are in-compatible, don't trash your HD DVD player just yet. It will still do a do job of playing the HD DVD discs you still have.
