Animating a back and forth walk cycle

[Joshea]

Hi,
I'm using an MH model for a catwalk scene in blender. Getting her to walk and strike a pose in one direction is easy. However I need her to walk back without using a nurbs path (makes it look like she's skating).
Has anyone else run into this problem?
I have a Mac, so editing a BVH file with BVH hacker is out of the question.
Any suggestions would be appreciated.

Try mocap data, i believe the cmu database is best, or whichever one I've been linking here (typing this on mobile). There should be mocap for it somewhere.
(and mhx2 seems to work best with makewalk)
