Retargetting in MotionBuilder

Hello! I need to retarget an animation set in MotionBuilder. Somebody has already prepared it quite well for me: He mapped my character, and it worked well on a single animation. I'm looking for somebody who can record a video of how to retarget the entire animation set and export it as an fbx. I think it's rather easy, but I'm too newbie, so I need a nice tutorial video. If you're interested, please send me a message, and I will provide you the mapped character and the animation set so that you can have a look. Thank you.
