HDRI Community

I was wondering if anyone has any experience with Vue 7.5 and creating sIBLs.  I know you can export a sky and a picture in .hdr but I do not know much else.  I was wondering if anyone here had any experience with this software and how they get sIBL Edit to work with it.

My biggest question is how are the environment, background, and reflection images differ and how would you generate these images with Vue 7.5.  Any help with this would be greatly appreciated.
