_ A blueray disc plays movies in a higher resolution (better quality) that can be seen on high definition televisions. You have to have a blueray player to play these discs. They hold much more data than regular dvds (about 10 times as much I think) Resolution and storage capacity.
Regular DVD's are 720x480 or 480p. Holds about 9GB.
BluRay DVD's are 1920x1080 or 1080p. Holds about 50GB.
Side Note: BluRay DVD's can only be played in BluRay DVD players. They can't be played in HD-DVD or DVD players. I myself am curious about blu-ray discs. I am doing some research for a school project on blu-ray discs. I do know that the blu-ray holds 50gigs on a double sided disc. It can have 9 hours of High-def video and 23 hours of standard dvd video. The players are expensive but the most inexpensive is integrated into Sony's PS3. Hope it helped! The Blu Ray dvd player uses a Blue laser to read the information from the disc as opposed to a standard DVD player which uses a more common Red Laser. The Blue laser is capable of picking up more info from the disc, hence the reason that Blu Ray discs can hold many times the information of a standard DVD. Toshiba's HD DVD uses the same technology, however the two formats are completely incompatible. A Blu Ray Disc will not play in an HD DVD player, and vice versa. The main differences are:
