trouble with mapping

[jsruk]

So...i've made the sphere and mapped the hdri on it (first picture), then i've placed plane poly for floor and mapped hdri on it like on the sphere(secont picture), but when i render that i get sh*t (picture 3), so i have to move down a bit plane polygon, then i finaly got something (picture 4), but when camera is above and under Y position=0m, render looks wierd, somehow distorted (picture 4 and 5), but when camera is on y position=0m, then render looks normaly (picture 6), wtf:?

Does someone know how to set this scene so i can move camera up and down without image distortion?

Thanks

This happens in max what i do:

Take a snapshot of the view where you want and make it like super big, then apply it to the envoironment slot so that its a still background and then just apply the original hdri file to the reflection shot.

I've tryed that but i that case i can't move camera

i know....in max you can redner the hdri map from the material ball,choose a nice place to render and render it out to any size.
