I've already given the recommended particular tutorial a go. Yes, I am sticking to Blender internal. The examples of node composition that I have previous included are my attempts at what I'm aiming for, at least.

I'm not trying to achieve a video fade. I'm trying to achieve a texture oriented fade to go along with an Animall shape key 3D morph transition. I want this to be based on textures or colours, either (though textures in my example). I have learned that one material on a surface or face can have two applied textures. I'm just trying to animate a turning down of the Influence colour (or alpha, if that will work) to fade away the upper one and reveal the lower one by default.

I can't seem to key key frame insertion or shape keys to do this, so I have surmised my answer is in the nodes compositor. However, I can't quite figure out how to build what I aim for from the nodes I see in composite mode. I also can't figure out how to apply my node graph to my relevant scene phenomena. For my example, I am trying to go from an upper red texture (turning that "down" or "off") to reveal the lower green texture. I think that I want to take one object's particular designated material, and then a designated Texture on that. What should I be aiming to be doing? The other thing is that I have a working blend file. It might be easier to email that to someone providing a working email address here, if they can include a solution.
