    Two things, really: Blu-Ray holds a lot more data, and they have a better protective coating, so resist damage better.

    Because they hold a lot more data, they can fit HD versions of movies on the Blu-Ray discs, taking full advantage of the high definition capabilities of modern HD TV's. If you have a HD TV, in most cases -- unless the studio was cheap and just dumped the DVD data to Blu-Ray, which I haven't heard of yet -- you should see a big difference in picture quality from DVD to Blu-Ray.

    If you have a standard old TV -- not a HD TV -- then you may not see much of a difference, other than additional extras often put on Blu-Ray (again, taking advantage of the extra space). Old TV's just are pretty low resolution, so you can't see much of the extra detail.

    Physically, there is nothing different between a DVD and Blu-Ray disc. It's all in the laser that is reading the disc. A Blu-Ray player uses a laser in the "blue" wavelength which is a much narrower beam and thus has a narrower track on the disc which allows more data to be written to the disc. Therefore a larger video format/resolution can be written to a Blu-Ray disc than a DVD. Also, they can include more extras (and previews).

    Blu-ray discs have a higher resolution, but they cost more.

    Unless you're a diehard movie buff, you won't notice too much difference between a DVD and a Blu-ray. (this does depend however on the kind of equipment you are using to play back the disc with. for example, watching a movie on a 19" tube TV means there won't be any noticable difference between DVD and Blu-ray)

    Blue Ray Disc movies are full high definition (1080P) while normal dvd's are not high definition (720P). You can't tell the difference between 720 & 1080P on screen size below 50". Blue Ray disc are alot more in detail in pictures than the 720P or below. It's like your old VHS tape compare to the DVD. Price are still high on Blue Ray Disc movies but they will eventually go down as time goes on, just like when DVD first came out.

    there is a big difference, in memory size. the blu ray also has way higher quality videos. and blu ray discs can hold around 50 gigs, and DVD's can only hold 4 gigs, and 7-8 for a dual layered one.

    A standard DVD is a simple menu system and contains Standard Def video (defined in 1945 for your Great Grandmothers TV).

    A BluRay disk contains high def video and is really a computer program written in a language called "BD Java". This allows you to have more interesting menus, picture-in-picture features, the ability to plug your BluRay player to the internet for more extras, etc.

    Hope this helps.

    They have a 1920X1080 resolution and use a blu laser in the player rather then red.

    You have to have a blu-ray player to play them. You can't play them in a reg. DVD player.
