Ha - the thread is back! :)

Is your projection matrix slightly different between OpenGL and Direct3D?
Yup, that's exactly right. The projection matrices (both the right-handed and left-handed versions) are the same for the two APIs except for a couple of elements that are computed differently due to the differing canonical view volumes.

Opengl fixed pipeline is dead, now all is made on vertex/fragment programs, also Directx, right handed or left handed depends on your projection matrix ONLY, you could use the same in both APIs.

Well, yes, that was kind of the whole point of the thread :)
