okay, I've wasted too many hours trying to figure this out myself.
I've created a cylinder and set it up as a multi/sub-object. The top and bottom of the cylinder are black and on the side I need an animation that looks like a scrolling billboard sign. I have the animation that I created in After Effects as an .mov animation. When I try to apply it to the cylinder, the top and bottom are fine but the side is a useless blurry mass of moving pixels that you cannot tell what it is supposed to be. I have tried adjusting the tiling, the size, the rotation...nothing works. I can get it to look alright in the material editor window but on the object it's a mess.
