I've attached the source for the second animation. This was created in blender 2.5, so to preserve the animation you have to open it with 2.5.
What, is there no way to convert them?
The base meshes without the subsurf modifier, yes. But that's really not much. The animation was done in blender 2.5, so opening this file in blender 2.49 will result in the loss of all keyframe information. And I doubt the animation can be easily exported to any other format. But if you want the base meshes without the subsurf, I can give you that.
