I think I know whats happening. In polygon, it might be because you didn't merge a lot of the vertices along the edges where you're getting ovals. When converting from poly to subD, all the edges tend to curve around which might be the problem you're having. And if you can't merge the verts, you might need to change the normals so that they're facing the same way(outwards) then merge.
