Cycles Nodes.

Add Plane,
Add material (use nodes).
Texture Coordinates > Mapping > Image Texture > Diffuse BSDF > Material.

Set Image Texture Node to Color>Flat>Image Sequence>Frames (4 in this example)> Cyclic (checked or not checked) > Auto Refresh checked.
Load Image Sequence (attached 4 image sequences 1,2,3,4).
Advance frame from 1 to 2 (for example)
Viewport rendering does not auto refresh on frame change. Only refreshes on parameter change.
(i.e. go into mapping parameter and come out, it refreshes).
