Blender animation not compatible.

Well some time ago I posted a question on here about motion capture and someone linked me to a site full of motion capture files but I have a problem.

The only format I see which is compatible with blender is the C3D format but when I import it the animation keys are not standard and so they are not compatible with my model exporter.

I tried to step through the animation and key the frames manually but that didn’t work, for some reason the way it is animated there is no rotation to key.

I don’t understand this type of animation, how can I convert it to standard key frames?
