I have a Mits 55819. I currently have my Toshiba DST-3000 plugged into the DTV input which is a component input. Does anyone know if the other component inputs will display HD 1080i?? Or do I have to keep the STB connected to the DTV input only. Also.....does anyone know why my geometry and convergence is messed up only on the DTV input?? I thought covergence and geometry are global. Another wierd thing is that when I converg the DTV input, it messes up my other compenent inputs...and vice versa. It's impossible for me to get them all correct. Any suggestions??
