video content played in a strange speed when using Matinee to output

When I import a video to the scene as a texture of material,and put it on a TV model,it seems all right in a matinee animation (using th Play button of the toolsbar to start the game and the matinee starts automatically)
But after I exporting the animation by the Movie button in matinee,the video played in a different speed and can’t display correctly。 Because it’s work in play model,and this problem only appear in a matinee output video file,so I thought it’s not caused by the hardware,is it right? Is there anybody have met the same problem before?
