Regardless of getting the lingo wrong, Youre right man. I have the same issue CS5. Its a bug. I tested it out in CS3 AE and regardless of how many times you push out a render it will render with the settings you choose. But in CS5 when you tell it you switch off field render it still randomly pushes out the render with upper/odd field. But its random as some times it will push out the exact same job with field render switched off as required. I checked the item properties of multiple renders in FCP, tested between CS3 and CS5 and without fail CS5 delivers a nice pole up the backend. Stuffed up days worth of work as I checked my settings and started rendering without checking the properties for every single render…why the hell would you?? I am totally pissed. I logged it adobe but the tech was not available so have to wait a few days..
