this question comes up here regularly and the answer is (still):
sorry, but none of the export modules to external renders
support textured surfaces yet. to get the best quality right
now you'll need a graphics card that fully supports GLSL and
turn that on.

the compression algorithms for movies usually produce so
many artefacts that the difference between a GLSL screenshot
and a rendered image is fairly small.
