ok i will tell you how i would design it from start..
1. I would create 2 frames..1 frame would have the play graphics and one would have the pause graphics..
2. I would put a button on that which will send the command PLAY (for pausing it is the same command) that button would just send the command - will not control the appearance of the movie...play or pause frame)
3. What will control whether play or pause will be shown, will be the "STATUS code check" you have written..which will run once a second. and will send the movie to the appropriate frame..
hope i helped
