When I finished the edition in page EDIT (an project with three movie) the order of the movies is set.
When I check to page Burning, in the Edit/Navigation an other order, an different order apears. I cannot change it in according to the original order.
So, you have loaded in three moveis and they are set in the order you want them burned... meaning one movie after another?
If this is not showing up correctly within the burn screen, then perhaps there is some issue with the naming of the files... I have not seen that before.
In the Edit/Navigation, highlight one of the films and move it up or down with the arrows..
