what's the difference between a normal DVD and a blu-ray DVD?

- Blu ray players range from $1500 for a Pioneer top-of-the-line player, to the $499 20GB Playstation 3. Any player in that range can play any available disc, and the quality of playback is very good even on the cheapest PS3 model.

- All blu ray players sold today can also playback DVDs. Most up-scale the DVDs to appear as good as they can on an HDTV.

- Blu ray discs are nearly always stored on disc at a resolution of 1920x1080 pixels. They are usually stored (for films) at a rate of 24 frames per second (same as film projection). Some video content is stored at 60 frames per second. DVDs are stored at around 720x540 pixels.

- Blu ray discs support more interactive content than DVDs such as Java applications, menus that can popup on top of the screen as a film runs, and so on.

- Blu ray discs have a special anti-scratch protective coating so they are less likely to get scratched, especially when you rent them or use Netflix. A DVD uses a red laser to scan the disc, and a Blu-ray uses a blue-violet ray. Because it has a shorter wave length, the picture is clearer. its like hd I have it on my ps3 the pic is breath taken
