Just some wild guesses: You might have to enable blending in the state set, and set an appropriate blend function as (depending on whether your projective texturing is done in a 2nd render pass or not)
On hardware that does not support opengl border colors (ARB_texture_border_clamp) in hardware, you might have to explicitly set the texture's border pixels to a transparent color, turning a 512x512 image into effectively a 510x510 one.
