Using an .avi for a transparency material

I have been having trouble adding a rotating checkerboard pattern avi as a transprency map for a texture, I slide the transparency slider over to white, then click the checker pattern to pick my avi file, and it jumps to black for some reason, and the transparency effect is not working. I got it to work once, but for some reason the slider keeps jumping back to black now, giving me 0% transparency effect.

any ideas as to what I am doing wrong?
