I have recently started working with an AG-HMX100. I have yet been able to pass SD video through, or for all I know into the switcher. The monitors (a multiview and a production montitor with all known formats available for input) will not read any input when you set up the switcher to 480i. I can not be sure that the video inputs on the switcher even work, since you can’t monitor any output from the switcher. Does this switcher even process or output SD?
