texturing an extruded curve

I can’t seem to properly align my image texture onto an extruded biezer curve. What I am trying to accomplish is a roll of film traveling through a projector. I made a bw map of a single frame with tractor holes. The idea is to repeat map this frame all along the curve. What I get is a series of horizontal bars, not my original image. What is different about the geometry of a curve as opposed to a regular mesh?

Thanks

I have same problem!
