So what are High Definition DVDs? well there two HD dvd formats that are being worked on as we speak one is called HD DVD and the other is called Blu-ray both of them support High defination films.

Something that is really incredible about these dvds is that the HD DVD will be a single layer capacity disk that will allow up to 15GB and then their will be a dual layer one that is 30GB. You might think that is pretty impressive but that isn't anything. Toshiba is in the process of developing a triple layer disk that will allow 45GB of data and then their will be a 100GB one that is four layer.. very impressive.

Basically high definition movies require more space and thats why companies are developing these high capacity disks to allow this to be possible.

What are the benefits of this?

Well this means DVD movies will have even more on them such as Directors comments, interactive features, out-takes and even a 2nd version of the dvd which will be in High Definition, I believe to fully benefit from this you would need a good tv and dvd player.

November 2004 was the start of talks saying that HD DVD would take over from regular dvds. Mind you blu-ray movies will require a Blu-ray player You should see both the HD DVD and Blu-Ray provide plent of space for high-definition movies this coming year.
