Do you need to play 3D blu ray disc on a 3D blu ray player to watch it in 3D or can I use a regular blu ray?

Will 3D blu rays come with an option to watch them in 2D?" All 3D content from Blu-ray and cable/satellite providers can be viewed in 2D mode if you want, it is a viewing option that you choose in a 3D TV's settings menu. "Will 3D blu rays work on regular blu ray players?"

Yes, the 3D Blu-ray specification was designed to be backward compatible with existing 2D Blu-ray players: http://www.maximumpc.com/article/news/ba... . "Have they hinted some type of exchange that we can make?" I have not heard of any exchange program like that.

There have been paid exchange programs for DVDs to spur Blu-ray sales, or free exchanges for initial Blu-ray releases that had poor transfers or transfer errors, but in this case the 3D version is a premium for you to purchase and not a transfer error.

Actually 3d blu-rays come with the 2d version on them as well. 3d blu-ray players can play regular blu-rays as well. You just can't play a 3d blu-ray disk on a regular blu-ray player.

It is very easy to get a 2d format from a 3d disk. You just play the right eye movie or left eye movie by itself. That is how they got the 2d format for Avatar.

So the 3d blu-ray disk has the 2d format already on it to begin with.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
