I find that it's better to build a basic geometry for your environment and spherically project your HDR onto it and then either use that geo as your environment for lighting/reflections, or do a panoramic render from the correct location within that geometry to get a correct HDR panorama. That way you don't have to be in the right place with the tripod, and still get perspectively correct reflections, which I can't imagine you would from simply transforming an environment image. Thorough on-set measurements helps of course :)
Btw, if you're on Softimage, surely MR is still in there lurking even in Arnold land?
