Hi. Just bought bdp790 and generally pretty pleased, but I need advice re a couple of issues if possible. When I watch a 3D blu ray, through my optoma hd131xe projector, the picture is much bigger than my 90" screen. I've gone into menu and put in 90" in the 'size of 3D screen' option, but this doesn't make any difference. Also changing 'auto and pan and scan' options doesn't make any difference either. Changing settings in projector menu also doesn't make any difference. With this issue I can't really watch 3D movies as the image spills out of screen onto wall and is really off putting. Any help would be very much appreciated. Secondly, and not sure if it's related, but some of my blu rays play with image in screen and black bars top and bottom letterbox style, which I like best (eg morrissey 25 live), but other blu rays (eg Hugo, les miserables) which on the box say are the same aspect ratio, completely fill my screen. Getting myself all confused about this! Would be grateful for some advice. Thanks.
