Ron,
A BluRay player can play a standard DVD, so long as the BluRay player has the DVD decoder software built into it. A DVD player does not have the Blue Laser and cannot play the BluRay at all. I have a Playstation 3, they are BluRay. Playstation 2 is DVD, The PS3 that had the 80GB hard drive included the software for DVD, so it can play PS2 games as well. You can also use it for a DVD and BluRay player.
