Questions/assumptions:
1. For full screen playback, once you’ve selected the monitor and closed the setting, you are clicking the full screen playback button and nothing happens, or it’s full screen on the wrong monitor?
2. I am assuming you have the right and most recent AMA plug-in for the material on the SxS card. You don’t mention camera or codec. Could be Sony as much as Arri. Also, there is a two folder directory limit, so make sure you are not to high in the hierarchy. And there are separate operations for folder versus clip when selecting AMA.
