(REPEAT FROM OTHER THREAD)
From the Flash 4 Help file:
Using QuickTime movies
When you import a QuickTime movie into Flash, the movie file does not become part of the Flash file. Instead, Flash maintains a pointer to the source file. You can scale, rotate, and animate a QuickTime movie in Flash. You can play and set the path of the movie in the Library.
When you import a QuickTime movie, only the first frame of the movie is displayed. For more information on publishing your Flash file as a QuickTime movie, see QuickTime publish settings.
To play a QuickTime movie:
1 Add the number of frames on the Timeline that correspond to the length of the QuickTime movie you want to play.
2 Choose Control > Play.
To set the path of a QuickTime movie:
1 Choose Window > Library and select the QuickTime movie you want to edit.
2 On the Options menu, choose Properties and click Set Path in the Video Properties dialog box.
3 Enter the new location of the QuickTime movie.
