One for the pros

Ok so heres the situation. I been reading over some tutorials and I now know how to give the object a realistic reflection by the use of a HDRI.

Now I seen a lot of you guys using a HDRI for you backgrounds. I've tried it a couple of times and it just not working. All the tutorials that I have read over example the reflection part but not how to create a 3d background with the use of a HDRI.

Can someone please, please help me out, either by showing me or directing me to a tutorial that I can study from.

3d program - 3D Studio Max 6
Render - Mental Ray
