I'm hopefully going to order a Panasonic PT-AE100 tomorrow but have a few small issues I'd love some feedback on: a) will it handle 4:3 images similarly to my old RPTV i.e. just centre within 16:9 frame with grey/black bars down the side b) I'm planning on getting a 106" (7 foot 8 inch by 4 foot 4 inch) roller screen, projector to screen distance is 13 foot max, I pressume the little beauty will fill it. c) on the subject of filling it, I pressume you can focus it in so that the edges are fairly precise in finishing at the black boarder of the screen. d) does composite and/or component input have auto 16:9 switching so it automatically changes ratio back and forth from 4:3 to 16:9 e) *MOST IMPORTANT* I've read about some problems with the fixed ceiling bracket, apparently there is only one (dedicated) type worldwide and it may not be upto the job, some guys projector's fell from the ceiling??? f) any idea of the cost of a replacement bulb, I heard about US$210 Thank's in advance, I don't know how I bought anything before the net!
