I added an FLVPlayback to timeline - it doesn't work right

When I test the Animate animation the two things happen. First the playback works up until the FLVPlayback in the timeline, then it plays less then a second of the FLVP I have AND it goes back to the beginning of the work (it's about 15 seconds long) and plays the sound from both and the pictures from the begining. How do I make it stop and just play in a streight line?

The work is a .mp4
