The first map above is not just a 2d normal map. It looks like a tangent space normal map and the second looks like an object space normal map. It really depends which one your shader supports. You can also create tangent space normal maps with 3d programs. The baking plugin from ATI (which is included with a wrapper module in Lightwave or Blender) allows to switch between tangent and object space normals.

So I would check that first.

Edit: Don't blame the engine for the shader or the wrong made normal map. That is just a very small part of the engine at all. It is just eye candy stuff that can be easily fixed. And the video with the room looks fine.
