i'm here again. i have the same problem with the flash video. i put the fps_min at 15, fps max at 17 and fps lock at 16 but the speed is diferent in other pcs. besides i use flash videos because the avi videos have a poor cuality. i render videos at 1024*768 and play it at 800*600 or with the same resolution, but always have the same problem. There is another video formta that works well with the engine? Also it seems that there are problems when the engine should have open two dll at the same time, in this case that of the flash and that of the own game. that I do?
