Thanks Calvin.... the IOCTL was previously working as u proposed. Was trying
to move it from miniport do D3D.
Incidentally, where can i get this information from? I havent found it in
the DDK, i am sure it's somwhere in there, but cant find it as yet. Do you
know where that piece of "black and white" is?. Thanks again so much.
