I will be purchasing a Panny Ae100 soon. Given the layout of the room I would have the option of rear projection. My screen will be mounted inside a square archway. There is enough room in the rear of that room to position the PJ for rear projection. Are rear projection screens suitable for home cinema or are they geared towards corporate presentations ? Are the screens available in pull down screens ? Does anybody have any views / experiences of rear projection set ups ? Thanks.
