I like the idea of using Rear Projection as the light will travel directly from the projector, to the back of the screen and then right to the eye. The concept of using a projector behind me to bounce off a screen and folding the optical path before it reaches my eye seems less ideal.
Since I have the room to put the projector behind the screen (113" width) I say why not. I believe that it should help in the overall ambiance to not have light in the viewing room more than is necessary.
Which screens, used for rear projection, is everyone having the best results with?
I'm like a lot of others in that I'm waiting until next year to purchase the projector so the projector currently is not a limiting factor as to which screen to get.
Another question is that if I place the center speaker also behind the screen I would have to place it far enough back as to not cast a shadow. Will I get a sync problem between audio and video if I do this? I think there are ways to adjust for the out-of-sync but I'm not sure.
