What are the new features of Blu Ray discs?Can someone tell me the difference between Blu Ray discs and DVDs?
Data-wise, a DVD and a blu-ray can hold the same types of data. In fact, they can contain any data you like, it's just a matter of finding a device that can read that disc to write or retrieve that data. A DVD can hold multimedia and data files... and a blu-ray can hold multimedia and data files... it's just that a blu-ray can hold many many more of them. Here's why:



I'm sure you've heard by now that blu-ray discs require the use of a blue laser to read the data. In fact, the primary reason for blu-ray's superiority is due to some breakthroughs in optical technology. The wavelength of the blue laser could be reduced to 405nm from the red laser's 650nm... meaning that basically the same amount of information could be stored and retrieved in a smaller area. Making the disc layer thinner and slightly increasing the laser aperture size eliminated unwanted spreading and bending of the light waves to keep it well focused.



-Yes, blu-ray is better both physically and capability-wise.



-The best blu-ray player overall is considered to be the PS3, as it supports all of blu-ray's capabilities. It took a while for Sony to release a firmware update that allowed decoding of DTS HD Master Audio, but it is now a full-featured profile 2.0 blu-ray player. The best standalone player is considered to be the Panasonic DMP-BD50.



-Features of blu-ray have yet to be fully unlocked. Of course the capacity allows for high bit-rate video at full high definition, and uncompressed audio. Everyone knows that (or should by now). But, with BD-Java programming capability and bringing the internet into it with BD-Live, the possibilities become astounding over DVD. I mean, it's not going to change your oil or balance your checkbook or anything... but, from an entertainment standpoint it's a pretty exciting medium. The movie companies finally have a medium with capabilities that can provide their customers with a full immersion experience in their living rooms.



DVD is the big brother and is still a damn good medium. But, moving into high definition and interactivity beyond that of navigation menus and Easter Eggs, DVD just doesn't cut it. However, there is no war between DVD and blu-ray. If there were, Sony would not have made it so all blu-ray hardware must support DVD. It's just a step-up from previous technology. I don't doubt that soon blu-ray and HVD (holographic versatile disc) will be in the same boat.
there's no argument: in virtually every case a bluray disc is better quality than a DVD. However Blu-ray discs are currently expensive so it makes sense to decide when to buy Bluray.

blue ray is more compressed than DVDs, so it hold more on one disc, so it has higher quality than regular DVDs....don't ask how i know that.
