MotionBuilder was created for this purpose; that is, to record animations for avatars. MotionBuilder is the tool that LiveCharacters lives in. Once recorded in MotionBuilder, you export the animation to 3ds Max and then export to CFG.

I bet you can record animations and run LiveCharacters in MotionBuilder at the same time if you want.

Another option would be to buypass 3ds Max and record all of the LiveCharacters's bone rotation in some data file with Vizard. Then read that data back to animate the character again.
