hello, i'm looking to buy the new pt-d4000, and i have a 3.2 meter distance from wall to wall. since after calculating the image size in 16/9 view i would like to get a larger image and therefor i would like to install the projector inside the back wall. my concern in 2 things, 1. heat. how ventilated does the area of the projector has to be? 2. and more concerning, it really depends how far in the back wall i will install it, but i'm worried that the receptor of the projector and the remote control will not "see" each other. is there an option to attach to the projector an extention to the receptor to a closer place to me? thank you, shachar.
