Can U tell what is the advantage of Blueray disk over a DVD?Why Blueray disk is not popular?which are of companies producing blueray disk?
The difference between a Blue Ray Disk and a DVD is something very simple, High Definition versus Standard Definition. on Blue Ray Disks, there are several things that are improved from the DVD Disks that allow for a High definition viewing of movies, for example, the size capabilities for blue ray disks is almost 5 times that of a normal DVD (4gigs to 25 gigs), so you can store a greater quality video on it. The data transfer rates have increased significantly (10Mbps to 54Mbps, higher resolution (480/576i to 1080i), the video bit rates have gone up 4 fold (i believe it's 8Mbps to 50Mbps (not sure on that one, but numbers are close)).All of these increased statistics allow for a High Definition viewing of movies on High Definition TV's.Blue ray disks probably aren't so popular right now, because it requires a special player, as well as a high definition TV to play it to it's full potential, and those kinds of things cost money, money that is slim right now in today's economy. I believe that all of the major film companies are producing blue ray disks for all of the movies they are putting out (Sony, Warner bro's, fox, etc..)

Yes Blu-ray makes a big difference, the media holds a lot more video data than DVD, the quality improvement is pretty awesome on LCD TVs. I would definitely recommend getting a Blu-ray player or a ps3 if you are a movie lover.
