IMHO 3D TV is different because the perception is very dependent on
the distance the two cameras are located from each other. Each person
has different distance between the two eyes and his/her brain is used
to interpreting the 3D picture based on that distance. So until you
come with a technology that can give you that same adjustment you will
have very few people that are lucky and they have the "average"
distance that the cameras are located one from another and the rest
that have all sorts of issues with 3D TV.
