I inserted a video (load external video with playback component) and inserted a tween, so that the video frame will move across the screen for the first second or so. If I go to control and click PLAY, everything goes as I want: the movie clip moves across the screen from the first position, then stabilize to the last position I want.
If I test the movie (Control, Test movie), then the movie clip stay at the first position and do not move to the position I want. If I publish the scene or porject, same result: no movement.
Thanks for the help
It's a long standing "Flashism" that components don't tween at runtime. You will need to wrap the component inside of a movieclip for it to tween.
