Mental Ray will only render sub-Ds whose base mesh is all quads. Thats what the error message you're getting is all about. If you get rid of any tris and any 5 sided (or more) polygons it will render just fine.

hi there .. it seems i had the same problem ..

here is the solution ..select your subD surface go to:
modeling==>edit sub-D surfaces-collaps hirarachy

then you will be able to render it with mental ray

wish you all the best bro ..
remeber to stay away from n-gons or more than four sided ploygons while modeling
