Sorry for another LT150 post. I've been playing around with my DTC100 HDTV tuner and the LT150. On 4:3 material, I am unable to fill the entire screen no matter what my settings are on the DTC100 (raster settings, screen format) or the LT150 (resolution, position/clock). It seems that the LT150 locks into a certain format when fed a 540p signal. The 1080i widescreen material seems to be correctly letterboxed. Has anyone else had similar results?
