Movie textures don't play with Alt-A

I have two different movie textures on two sides of a cube object. They show up fine in the texture display mode of the 3d view window. But pressing Alt-A doesn’t animate the movies. They do animate if I scrub on the timeline, but they don’t play. Cycles render by the way. Is there a way to see the “live” movie play before rendering?

Your image texture node should be selected to see texture preview in Material view. By changing head position in Timeline texture shows proper frame on the object. If each face has it’s own material you can not see two textures changing at once.
