mirror pose = weird rotations

Hi everyone!

Iam tring to make a walkcicle able to work inside the gamengine, so iam using insert > locrot for it.

Iam in trouble when i mirror the poses and change the number of frames: it works fine if i have just one frame per movement, but if i increase the number of frames some weird rotations start to hapen between movements.

Any help?

Thanks.
