I have a 2 year old Toshiba TN61X81. It is a 4:3 set capable of 1080i display. I have just purchased (but not yet received) the Samsung SIR-T150 STB. My question is will the system display a letterboxed picture of correct proportions when receiving a 1080i signal off the air, or will the picture fill the entire screen (i.e. be vertically "stretched"). Best I can tell from literature and posts, the letterbox, zoom, etc. options cannot be applied to 1080i ouput. Anybody have any experience with the T150 and a set that cannot do the "anamorphic squeeze"? Thanks in advance.
