Do you plan to use MLT filters or transitions? There is a way to do what you want, but I think only when not using existing MLT filters and transitions. If I recall correctly, you have to suppress the normalization filters that the loader producer automatically adds. Then, if you do include other MLT filters or transitions, they might be very unhappy with non-conformed dimensions. Basically, you are headed into dangerous territory, and you should abandon nearly all MLT modules except perhaps xml if you want to support MLT XML.
