Writer - EX9.Texture AVI produces a blank video?

When I use the node Writer - EX9.Texture AVI to save the texture connected to an AVI file, I get a video with only a black screen ?

Even the simple patch described in the help file (Writer (EX9.Texture AVI) help.v4p) seems not working.

Check the number of frames and the texture size. Try to use a small one at beginning like 320x240.
