what is the differnts between blue ray and regular dvd?

The most notable difference is the laser that is used to read the media from the DVDs.

Blu-Ray DVD players use, of course, blue rays to read & regualr DVD players use red.

This makes Blu-Ray players backwards compatible but not vice versa.

Increased video Resolution : The Blu-Ray disk offers 480p, 720p and 1080i resolutions.

Better video codec support : MPEG-4 AVC High Profile and VC-1 will be supported, in additional to the MPEG-2 format used by current DVDs.

Enhanced graphics : More than one graphics plane - one plane could be used to display closed captioning, while the other can still show a user menu.

Simultaneous video and graphics : In a DVD, if you select the root menu while playing video, the video stops to show the menu. The Blu-Ray disk can continue to play the video while you browse through the menu options.

Interactivity : With Java included in the Blu-Ray player, interactive applications and content (such as games) may be played from the disk.

Network connectivity: This may be used to get disk content related additional material from the web, directly from the player. For instance, the disk can link to updated material on the network after the disk is released. This gives a richer user experience while watching a movie, for downloading movie extras, reviews and games.

hey well i'm definately not an expert and was woundering the same thing so now i know a bit more also..

but basically it tells you that blue ray DVD's

-use a blue-violet laser to read and write onto the disk

-5times the storage capacity of normal DVD's

-provides high definition

-shorter wavelength meaning the laser can focus precisely making it better quality

-fit more in a disk even though its the same size as a normal DVD or CD

Regular DVD's hold less information so they can not store High Definition video. Blue Ray uses a different type of disc to store more information so it can store longer and larger video files.

you could play a typical dvd in a blu ray participant, although you could no longer play a blu ray disc in a typical dvd participant. you will would desire to get a blu ray participant. Blu ray is a severe definition format for dvd's. for sure you're able to would desire to have a HDTV to view the action picture in severe definition. It makes the journey that greater captivating than usual definition. typical dvd's seem close to severe definition standards in a blu ray participant. It has lots greater constructive components than a typical dvd. particular video clips will come interior the blu ray format. There are dvd gamers that play the two formats, yet you're conversing over a one thousand greenbacks for it.

Well once you watch a blu-ray movie you wont be able to go back to regular DVD's.

So if you have a really good TV then just grab a PS3 or Blu-Ray player.

Trust me everything is just sooooooooo much better.

Blue ray is a form of high definition, which you can only see on a high-def TV. Watching it on a non-high-def TV is like watching a color show on a black and white TV. There is also HDDVD, but it is losing out to blue ray.

Blu-Ray is High Definition video, and is played on Blu-Ray players.

DVDs can be played in DVD and Blu-Ray players and are not as high quality as Blu Ray discs.

blue ray is a high definition player if u are going to buy 1 i sergest to but a ps3 they are built in and a lot cheaper

enhanced graphics and better picture. kinda like regular tv and hi def tv
