Reflections and spherical texture

Hello vvvorums,
I got a sphere feeding the reflection shader with a videtexture and I need the texture to be spherical: the whole texture covering the surface. At the moment I have 8 textures, in a kind of kaleidoscopic effect. How can I get a spherical mapping on that sphere?
Thanks!!
