Is there a way to have two pdf's open with two different videos playing at the same time? If the answer is yes, could the videos be sync'd, I.E. start and stop ff and rewind together from one controller? The two videos should be sync'd at the desired starting points as well. The application for this could be something like, one video of building plans, the 2nd video of actual walk-through of the building. A marker would show and move with the location on the plans that corresponds with the walk-through video.
