Blu-Rays are used only for high definition. Blu-Rays hold up 5 times more data than a DVD can hold. Blu-Rays have capabilities that are way ahead of DVDs, such as accessing the bonus material while watching the movie

∙ 15y agoThe main difference is the color of the laser used. Regular DVD players have used the traditional red laser, whereas the new Blu-Ray DVD players use an innovative blue laser. So what's the big deal? The primary difference is that blue light has a shorter wavelength than red light and thus allows the capability of faster speeds, more data storage, advances in miniaturization, and improved efficiency overall, among others. The blue laser light is emitted by GaN semiconductors, which are very expensive to produce and extremely rare. The first blue laser was produced by Dr. Shuji Nakamura in late 1999 in Nichia Chemical Corporation Laboratories. _________________________________________________________________________________________ Picture resolution. A regular DVD player in the U.S. is what's called an NTSC player and has 525 lines of resolution. The HD DVD has 700 to 1080 lines of resolution, depending on the way the disk was burned.

∙ 10y agoBlu Ray Discs are able to hold more data which in turn means it is capable of holding HD copies, which if you have a HD TV will mean a greater quality viewing. Regular DVD just has normal resolution although the difference can only be seen if the TV is not an old standard one.

What kind of DVD player will play HD DVDs?
To play a high definition DVD, you need a high definition DVD player. There are two types available currently. HD DVD, developed by Toshiba is one and BluRay, developed by Sony is the other. They are not compatible, so an HD DVD will not play on a BluRay player and a BluRay disc will not play on an HD DVD player. BluRay looks like it is the winner in the format war between the two companies over the last years so it is likely that Toshiba's format will disappear in the coming months. Note that HD DVD can refer to the Toshiba format but it can also refer to high definition DVDs in general.
